INTRODUCTION┆e1┆↲ ↲ ┆84┆The RC855 Display Terminal is designed for the construc┄↓ ┆19┆┆89┆┄┄tion of distributed systems in which each display termi┄↓ ┆19┆┆89┆┄┄nal in a cluster configuration can be used interchange┄↓ ┆19┆┆89┆┄┄ably for communication with a host computer and as a ↓ ┆19┆┆89┆┄┄local microcomputer system.↲ ↲ ┆84┆The RC855 is a member of the RC850 family of intelligent ↓ ┆19┆┆89┆┄┄display terminals. The use of a microcomputer as the ↓ ┆19┆┆89┆┄┄basis of all RC850 display terminals makes it possible ↓ ┆19┆┆89┆┄┄to emulate a number of different terminals on the market ↓ ┆19┆┆89┆┄┄as well as to execute a variety of local terminals exist ↓ ┆19┆┆89┆┄┄accordingly in several different versions.↲ ↲ ┆84┆The RC855 is in principle a soft-programmed version: a ↓ ┆19┆┆89┆┄┄versatile work station, which can be alternately loaded ↓ ┆19┆┆89┆┄┄with communication programs and programs for local ↓ ┆19┆┆89┆┄┄applications from an attached diskette drive.↲ ↲ ↲ ┆b0┆┆a1┆1.1 Cluster Concept┆e1┆↲ ↲ ┆84┆The RC890/RC855 cluster consists of a RC890 Control Unit ↓ ┆19┆┆89┆┄┄(CU) and a number of RC855 terminals which are program┄↓ ┆19┆┆89┆┄┄med as IBM 3270 Display Stations. The RC890 Control Unit ↓ ┆19┆┆89┆┄┄permits the RC855 terminals to access host systems ↓ ┆19┆┆89┆┄┄utilizing the SNA/SDLC as well as the BSC protocol for ↓ ┆19┆┆89┆┄┄remote connection of IBM 3270 Display Stations. The ↓ ┆19┆┆89┆┄┄RC855 terminals are connected to the CU by means of a ↓ ┆19┆┆89┆┄┄multidropped terminal network, called RcCircuit.↲ ↲ ┆84┆Application programs for RC855 terminals connected to ↓ ┆19┆┆89┆┄┄the RC890 Control Unit are downline loaded from disk┄↓ ┆19┆┆89┆┄┄ette, after optional selection from a menu.↲ ↲ ┆84┆Further information on the RC890 Control Unit can be ↓ ┆19┆┆89┆┄┄found in reference (1).↲ ↲ ↲ ┆b0┆┆a1┆1.2 Terminal Configuration┆e1┆↲ ↲ ┆84┆The functioning of the terminal running the IBM 3270 ↓ ┆19┆┆89┆┄┄emulator is affected by a number of configuration param┄↓ ┆19┆┆89┆┄┄eters. These parameters may be changed under program ↓ ┆19┆┆89┆┄┄control. Modification of the configuration parameter ↓ ┆19┆┆89┆┄┄values takes place by a seperate configuration program ↓ ┆19┆┆89┆┄┄before the emulator is started. The configuration param┄↓ ┆19┆┆89┆┄┄eter values are stored in the non-volatile memory, which ↓ ┆19┆┆89┆┄┄means they are kept permanently, also when the terminal ↓ ┆19┆┆89┆┄┄is powered down.↲ ↲ ┆84┆A few of the configuration parameter values may also be ↓ ┆19┆┆89┆┄┄changed after the emulator has been started. Configur┄↓ ┆19┆┆89┆┄┄ation parameters are described in more detail in sec┄↓ ┆19┆┆89┆┄┄tions 7.2.2 and 6.5.↲ ════════════════════════════════════════════════════════════════════════ ↓ ┆b0┆┆a1┆1.3 Emulator Operation↲ ↲ ┆84┆A cluster of RC855 terminals running the IBM 3270 BSC ↓ ┆19┆┆89┆┄┄emulator programs will communicate with a host computer ↓ ┆19┆┆89┆┄┄in the same fashion as an IBM 3270 cluster control unit ↓ ┆19┆┆89┆┄┄using the BSC or SNA/SDLC communication line discipline.↲ ↲ ┆84┆From the operator point of view, each terminal in the ↓ ┆19┆┆89┆┄┄cluster works as an IBM 3277 model 2 display station. ↓ ┆19┆┆89┆┄┄However, the RC855 keyboard has a different layout and ↓ ┆19┆┆89┆┄┄certain extensions when compared with the corresponding ↓ ┆19┆┆89┆┄┄IBM typewriter keyboard.↲ ↲ ┆84┆A 3270 oriented application program in the host computer ↓ ┆19┆┆89┆┄┄communicates with the operator through a series of ↓ ┆19┆┆89┆┄┄display screen images. An image of the data transmitted ↓ ┆19┆┆89┆┄┄from the host is displayed at the terminal. By means of ↓ ┆19┆┆89┆┄┄the keyboard, the operator can enter, modify, or erase ↓ ┆19┆┆89┆┄┄data on the display, and cause the revised data to be ↓ ┆19┆┆89┆┄┄returned to the host for storage or further processing. ↓ ┆19┆┆89┆┄┄Printed copy of data displayed at a terminal or trans┄↓ ┆19┆┆89┆┄┄mitted from the host may be provided by an attached ↓ ┆19┆┆89┆┄┄printer.↲ ↲ ┆84┆Normally the application program supplies a "form" for ↓ ┆19┆┆89┆┄┄the operator to fill in and return. A formatted screen ↓ ┆19┆┆89┆┄┄image consists of protected fields containing guide ↓ ┆19┆┆89┆┄┄texts and unprotected fields for user input. Each screen ↓ ┆19┆┆89┆┄┄image field begins with a socalled attribute character, ↓ ┆19┆┆89┆┄┄which occupies a character position on the display, but ↓ ┆19┆┆89┆┄┄is shown as a blank.↲ ↲ ┆84┆The operator may cause information to be transmitted to ↓ ┆19┆┆89┆┄┄the host computer (application program) by pressing an ↓ ┆19┆┆89┆┄┄attention key. Pressing a data attention key, i.e. SEND ↓ ┆19┆┆89┆┄┄or PF, causes the contents of modified fields on the ↓ ┆19┆┆89┆┄┄display to be transmitted.↲ ↲ ┆84┆By attaching one or more printers to the cluster it is ↓ ┆19┆┆89┆┄┄possible to obtain data printouts of the screen images ↓ ┆19┆┆89┆┄┄or from the host computer directly.↲ ↲ ┆84┆Detailed information on how a particular application ↓ ┆19┆┆89┆┄┄uses the 3270 features must be found in the operating ↓ ┆19┆┆89┆┄┄guide for the application in question. Note in parti┄↓ ┆19┆┆89┆┄┄cular that the meaning of PA and PF keys is application ↓ ┆19┆┆89┆┄┄dependent.↲ ↲ ┆84┆When the emulator is running all operator control is ↓ ┆19┆┆89┆┄┄performed from the keyboard as described in chapter 2.↲ ↲ ════════════════════════════════════════════════════════════════════════ ↓ ┆b0┆┆a1┆2.╞ OPERATIONAL CHARACTERISTICS↲ ↲ ┆84┆The RC855 IBM 3270 Emulator supports format oriented ↓ ┆19┆┆89┆┄┄communication between the terminal operator and an ↓ ┆19┆┆89┆┄┄application program runnning on a host computer. The ↓ ┆19┆┆89┆┄┄basis of this communication is the transfer of a ┆a1┆message┆e1┆ ↓ ┆19┆┆89┆┄┄from the application towards the terminal (outbound) or ↓ ┆19┆┆89┆┄┄from the terminal towards the application (inbound). A ↓ ┆19┆┆89┆┄┄message consists of a string of 8-bit characters. A ↓ ┆19┆┆89┆┄┄┆a1┆character┆e1┆ may be an alphameric or a control character, ↓ ┆19┆┆89┆┄┄or it may be a binary encoded (e.g. a buffer location) ↓ ┆19┆┆89┆┄┄or encoded in subfields (e.g. an attribute character).↲ ↲ ┆84┆For each device, i.e. terminal or printer, the Emulator ↓ ┆19┆┆89┆┄┄maintains a ┆a1┆device buffer┆e1┆ containing 1920 character ↓ ┆19┆┆89┆┄┄positions. For a terminal the buffer is organized as 24 ↓ ┆19┆┆89┆┄┄lines, each containing 80 character positions. For a ↓ ┆19┆┆89┆┄┄printer it is also possible to use other line length or ↓ ┆19┆┆89┆┄┄no fixed line length. The image shown on a display ↓ ┆19┆┆89┆┄┄screen as well as the lines printed on a printer are ↓ ┆19┆┆89┆┄┄always determined by the contents of the relevant device ↓ ┆19┆┆89┆┄┄buffer. Each character in a device buffer is either an ↓ ┆19┆┆89┆┄┄attribute character or a data character.↲ ↲ ┆84┆An ┆a1┆attribute character┆e1┆ indicates the start of a display ↓ ┆19┆┆89┆┄┄field extending to the next attribute character, and ↓ ┆19┆┆89┆┄┄defines the attributes of the field:↲ ↲ o ┆84┆alphameric input, numeric input, protected, or ↓ ┆19┆┆8d┆┄┄automatic skip↲ o ┆84┆normal display, cursor selectable,intensified dis┄↓ ┆19┆┆8d┆┄┄play and cursor selectable, or nondisplay↲ o flashing or not flashing↲ o modified or not modified↲ ↲ ┆84┆An attribute character occupies the first position of a ↓ ┆19┆┆89┆┄┄display field, but appear as a blank position on the ↓ ┆19┆┆89┆┄┄screen. The contents of an attribute character can be ↓ ┆19┆┆89┆┄┄displayed in the reveal mode. Attribute character are ↓ ┆19┆┆89┆┄┄protected.↲ ↲ ┆84┆A field with the alphameric input or numeric input ↓ ┆19┆┆89┆┄┄attribute is unprotected against manual input and there┄↓ ┆19┆┆89┆┄┄fore called an ┆a1┆input field┆e1┆. All character positions ↓ ┆19┆┆89┆┄┄following the attribute character in an input field are ↓ ┆19┆┆89┆┄┄called ┆a1┆input positions┆e1┆. A field which is not an input ↓ ┆19┆┆89┆┄┄field is called a ┆a1┆protected field┆e1┆. The modified/not ↓ ┆19┆┆89┆┄┄modified bit in the attribute character is called the ↓ ┆19┆┆89┆┄┄┆a1┆modified data tag┆e1┆, or MDT.↲ ↲ ┆84┆A ┆a1┆data character┆e1┆ may be any of the following: an alpha┄↓ ┆19┆┆89┆┄┄meric character, null character, DUP character, FM ↓ ┆19┆┆89┆┄┄character, or printer control character.↲ ↲ ════════════════════════════════════════════════════════════════════════ ↓ ┆84┆One should bear in mind the difference between the null ↓ ┆19┆┆89┆┄┄character and the space character. Space is a well-↓ ┆19┆┆89┆┄┄defined alphameric character, whereas null is an all-↓ ┆19┆┆89┆┄┄binary-0 character. Both occupy a position in the device ↓ ┆19┆┆89┆┄┄buffer and are displayed as a blank position, but null ↓ ┆19┆┆89┆┄┄is suppressed in the transfer of a message.↲ ↲ ┆84┆The most common outbound messages are write-type com┄↓ ┆19┆┆89┆┄┄mands, which instruct the Emulator to modify the con┄↓ ┆19┆┆89┆┄┄tents of a device buffer in a specified manner. Simil┄↓ ┆19┆┆89┆┄┄arly, most inbound messages are ┆a1┆read messages┆e1┆ which ↓ ┆19┆┆89┆┄┄convey information from the Emulator about the current ↓ ┆19┆┆89┆┄┄contents of a device (i.e. terminal) buffer, in ↓ ┆19┆┆89┆┄┄particular fields that have been modified by the oper┄↓ ┆19┆┆89┆┄┄ator. The part of the message that contains detailed ↓ ┆19┆┆89┆┄┄information about the device buffer consists of device ↓ ┆19┆┆89┆┄┄buffer orders and device buffer data.↲ ↲ ┆84┆┆a1┆Device buffer orders┆e1┆ in outbound messages are used to ↓ ┆19┆┆89┆┄┄indicate the buffer locations of the following device ↓ ┆19┆┆89┆┄┄buffer data, to set attribute characters, or to request ↓ ┆19┆┆89┆┄┄some additional function (e.g. tabulation). In inbound ↓ ┆19┆┆89┆┄┄messages, device bufer orders are used exclusively to ↓ ┆19┆┆89┆┄┄indicate the buffer locations and attribute characters ↓ ┆19┆┆89┆┄┄of transferred fields.↲ ↲ ┆84┆┆a1┆Device buffer data┆e1┆ in outbound messages is that which is ↓ ┆19┆┆89┆┄┄to be written in the device buffer as data characters. ↓ ┆19┆┆89┆┄┄In inbound messages, device buffer data conveys the data ↓ ┆19┆┆89┆┄┄characters in transferred fields.↲ ↲ ════════════════════════════════════════════════════════════════════════ ↓ ┆b0┆┆a1┆3. DISPLAY TERMINAL↲ ↲ ┆b0┆┆a1┆3.1╞ Data Presentation↲ ↲ ┆84┆Data stored in the device (terminal) buffer is displayed ↓ ┆19┆┆89┆┄┄on the screen in the form of alphameric characters. The ↓ ┆19┆┆89┆┄┄terminal operator can enter alphameric characters into ↓ ┆19┆┆89┆┄┄the buffer from the attached keyboard. The application ↓ ┆19┆┆89┆┄┄program provides a formatted display by storing attri┄↓ ┆19┆┆89┆┄┄bute characters in the buffer. The attribute characters ↓ ┆19┆┆89┆┄┄in turn define the display fields, including those for ↓ ┆19┆┆89┆┄┄which the operator can manually enter, modify, or erase ↓ ┆19┆┆89┆┄┄data (input fields). As all locations in the buffer can ↓ ┆19┆┆89┆┄┄be addressed individually, a display field can start at ↓ ┆19┆┆89┆┄┄any character position.↲ ↲ ┆e1┆┆e1┆┆e1┆ ╞ ┆a1┆┆e1┆ ┆a1┆Cursor↲ ┆84┆The cursor is a unique symbol that identifies a char┄↓ ┆19┆┆89┆┄┄acter position on the display screen, usally the loca┄↓ ┆19┆┆89┆┄┄tion at which the next character to be entered from the ↓ ┆19┆┆89┆┄┄keyboard will appear. The form of the cursor is defined ↓ ┆19┆┆89┆┄┄by a configuration parameter. The movement of the cursor ↓ ┆19┆┆89┆┄┄is described in detail in chapter 4. ↲ ↲ ↲ ┆b0┆┆a1┆3.2 ┆a1┆Screen Orientation↲ ↲ ┆84┆The terminal can operate in two modes: left to right ↓ ┆19┆┆89┆┄┄orientation and right to left orientation. The mode ↓ ┆19┆┆89┆┄┄depends of a configuration and setup parameter. (See ↓ ┆19┆┆89┆┄┄subsection 7.2.2 and section 6.5).↲ ↲ ┆84┆In the left to right operation the contents of the first ↓ ┆19┆┆89┆┄┄position in the devicebuffer is shown in the upper left ↓ ┆19┆┆89┆┄┄corner of the screen. In the right to left operation the ↓ ┆19┆┆89┆┄┄content of the first position in the devicebuffer is ↓ ┆19┆┆89┆┄┄shown in the upper right corner of the screen.↲ ↲ ┆84┆In the left to right operation latin text will be writ┄↓ ┆19┆┆89┆┄┄ten from left to right, and the cursor moves to the ↓ ┆19┆┆89┆┄┄right. If swop to the arabic mode by pressing the LATIN ↓ ┆19┆┆89┆┄┄key, arabic text will be entered from right to left by ↓ ┆19┆┆89┆┄┄moving the entered arabic text to the right without ↓ ┆19┆┆89┆┄┄cursor movement. Arabic digits will perform the same ↓ ┆19┆┆89┆┄┄movement to the right of the text, but now the cursor ↓ ┆19┆┆89┆┄┄moves to the right. By pressing the LATIN key again the ↓ ┆19┆┆89┆┄┄cursor jumps over the arabic text to continue with latin ↓ ┆19┆┆89┆┄┄text.↲ ↲ ┆84┆In the right to left operation arabic text will be ↓ ┆19┆┆89┆┄┄written from right to left, and the cursor moves to the ↓ ┆19┆┆89┆┄┄left. If swop to the latin mode by pressing the LATIN ↓ ┆19┆┆89┆┄┄key, latin text will be entered from left to right by ↓ ┆19┆┆89┆┄┄moving the entered latin text to the left without cur┄↓ ┆19┆┆89┆┄┄sormovement. By pressing the LATIN key again the cursor ↓ ┆19┆┆89┆┄┄jumps over the latin text to continue with arabic text. ↓ ┆19┆┆89┆┄┄Arabic digits will be entered from left to right by ↓ ┆19┆┆89┆┄┄moving the digits to the left without cursor movement.↲ ════════════════════════════════════════════════════════════════════════ ↓ ┆b0┆┆a1┆3.3 Character Presentation Modes↲ ↲ ┆84┆The picture shown on the screen is a presentation of the ↓ ┆19┆┆89┆┄┄contents of the device buffer. A character in the buffer ↓ ┆19┆┆89┆┄┄is shown as a graphic image on the screen.↲ ↲ ┆84┆As the EBCDIC code set does not contain all presenta┄↓ ┆19┆┆89┆┄┄tions of the arabic characters, the terminal has a ↓ ┆19┆┆89┆┄┄built-in context analysis in order to produce the cor┄↓ ┆19┆┆89┆┄┄rect arabic text. This facility can be switched on and ↓ ┆19┆┆89┆┄┄off by means of a configuration parameter (see sections ↓ ┆19┆┆89┆┄┄7.2.2 and 6.5). If the parameter called Arabic Display ↓ ┆19┆┆89┆┄┄Mode is set to zero, the contents of the device buffer ↓ ┆19┆┆89┆┄┄is shown with no change (i.e. no context analysis); if ↓ ┆19┆┆89┆┄┄it is set to one, context analysis is enabled to get the ↓ ┆19┆┆89┆┄┄correct arabic image.↲ ↲ ↲ ┆b0┆┆a1┆3.4 Status Information↲ ↲ ┆84┆The 25th line of the display is used for status informa┄↓ ┆19┆┆89┆┄┄tion.

The conversion is described in appendix E.↲ ↲ ┆84┆Arabic letters will always be entered from right to ↓ ┆19┆┆89┆┄┄left. If in left to right screen orientation arabic mode ↓ ┆19┆┆89┆┄┄has temporarily been selected by pressing the LATIN key, ↓ ┆19┆┆89┆┄┄the arabic test will appear on the screen as follows: ↓ ┆19┆┆89┆┄┄First time an arabic character is entered, it will ↓ ┆19┆┆89┆┄┄appear at the place of the cursor, which will ┆a1┆not┆e1┆ move. ↓ ┆19┆┆89┆┄┄When the following characters are entered, the previous┄↓ ┆19┆┆89┆┄┄ly typed characters will move to the right, and the new ↓ ┆19┆┆89┆┄┄characters are inserted at the place of the cursor, ↓ ┆19┆┆89┆┄┄which still does not move. When the operator wants to ↓ ┆19┆┆89┆┄┄return to latin mode, he must press the LATIN key, and ↓ ┆19┆┆89┆┄┄at this time the cursor jumps to the first free position ↓ ┆19┆┆89┆┄┄to the right of the arabic text just inserted.↲ ↲ ┆84┆Arabic numerals are always entered from left to right. ↓ ┆19┆┆89┆┄┄Suppose the screen orientation as well as the keying ↓ ┆19┆┆89┆┄┄directionis right to left and arabic digits are entered. ↓ ┆19┆┆89┆┄┄As before, the cursor will remain at its position, ↓ ┆19┆┆89┆┄┄digits already typed will move to the left and the new ↓ ┆19┆┆89┆┄┄digits will be inserted at the cursor position.

In this mode it is possible to ↓ ┆19┆┆89┆┄┄enter latin letters, latin numerals and a number of ↓ ┆19┆┆89┆┄┄special symbols.↲ ↲ ┆84┆In the latin mode the SPEC SHIFT key functions as the ↓ ┆19┆┆89┆┄┄SHIFT key. In latin mode we use the lefthand side of the ↓ ┆19┆┆89┆┄┄engravings on the keytops. When two symbols are engraved ↓ ┆19┆┆89┆┄┄here, the upper one is selected by using the SHIFT key. ↓ ┆19┆┆89┆┄┄When only one engraving is present (this applies for the ↓ ┆19┆┆89┆┄┄letters A-Z), no shift will enter the lower case latin ↓ ┆19┆┆89┆┄┄letter, and holding SHIFT down when pressing the key ↓ ┆19┆┆89┆┄┄will enter the upper case latin letter. However, if the ↓ ┆19┆┆89┆┄┄keyboard lock parameter is set to one (see sections 6.5 ↓ ┆19┆┆89┆┄┄and 7.2.2), all latin letters will appear as upper case. ↓ ┆19┆┆89┆┄┄The question of lower and upper case has only local ↓ ┆19┆┆89┆┄┄significance, as a limitation in the host prototcol does ↓ ┆19┆┆89┆┄┄not allow lower case letters, and therefore these are ↓ ┆19┆┆89┆┄┄converted to the corresponding upper case letters before ↓ ┆19┆┆89┆┄┄transmission.↲ ↲ ════════════════════════════════════════════════════════════════════════ ↓ ┆84┆In right to left screen orientation, insertion of latin ↓ ┆19┆┆89┆┄┄characters takes place in a similar way as discussed ↓ ┆19┆┆89┆┄┄above: latin mode is entered by pressing the LATIN key, ↓ ┆19┆┆89┆┄┄that hereby lights. From now on the cursor will not ↓ ┆19┆┆89┆┄┄move, but the latin text will move to the left as it is ↓ ┆19┆┆89┆┄┄entered.

CONFIGURATION PARAMETERS↲ ↲ ┆84┆A number of configuration parameters are stored within ↓ ┆19┆┆89┆┄┄each RC855 terminal. This is done using a non-volatile ↓ ┆19┆┆89┆┄┄memory which retains its contents over time, also when ↓ ┆19┆┆89┆┄┄the terminal is powered down.↲ ↲ ┆84┆When an RC855 terminal is installed, all configuration ↓ ┆19┆┆89┆┄┄parameters should be set appropriately. Normally this is ↓ ┆19┆┆89┆┄┄done by the installation staff. However, the description ↓ ┆19┆┆89┆┄┄in the following enables the user to modify the confi┄↓ ┆19┆┆89┆┄┄guration parameters as desired. The parameters are ↓ ┆19┆┆89┆┄┄described in section 7.2.2.↲ ↲ ↲ ┆b0┆┆a1┆7.1 Cluster Concept↲ ↲ ┆84┆Up to 32 RC855 terminals can be connected to the RC890 ↓ ┆19┆┆89┆┄┄Control Unit for connection to a BSC or SNA/SDLC com┄↓ ┆19┆┆89┆┄┄munication line as a 3270 cluster. The configuration ↓ ┆19┆┆89┆┄┄aspects of the cluster concept are outlined in the ↓ ┆19┆┆89┆┄┄following.↲ ↲ ┆84┆The terminals in a cluster are connected to the control ↓ ┆19┆┆89┆┄┄unit by means of RcCircuit. In order for this intercon┄↓ ┆19┆┆89┆┄┄nection to work correctly, each terminal must be confi┄↓ ┆19┆┆89┆┄┄gured with a unique secondary address (numbered from ↓ ┆19┆┆89┆┄┄zero. The secondary address has nothing to do with the ↓ ┆19┆┆89┆┄┄3270 concept of device numbering.↲ ↲ ↲ ┆b0┆┆a1┆7.1.1 Device Addressing↲ ↲ ┆84┆A device within a cluster is either a display or a ↓ ┆19┆┆89┆┄┄printer. In a 3270 cluster consisting of RC855 terminals ↓ ┆19┆┆89┆┄┄a printer is always physically attached to a particular ↓ ┆19┆┆89┆┄┄display terminal. Logically, however, it has no special ↓ ┆19┆┆89┆┄┄connection to the terminal to which it is attached. It ↓ ┆19┆┆89┆┄┄is available as a general resource for the whole clus┄↓ ┆19┆┆89┆┄┄ter.↲ ↲ ┆84┆Every device in the cluster has a device number (0 ↓ ┆19┆┆89┆┄┄through 31) which is used to identify the device both in ↓ ┆19┆┆89┆┄┄communication with the host and internally in the clus┄↓ ┆19┆┆89┆┄┄ter, i.e. for selection of a hard copy printer. The ↓ ┆19┆┆89┆┄┄device number should be chosen in agreement with the ↓ ┆19┆┆89┆┄┄host computer system support staff.↲ ↲ ┆84┆Every display terminal must be configured with its own ↓ ┆19┆┆89┆┄┄device number, the ┆a1┆display device number┆e1┆, and the ┆a1┆prin┄↓ ┆19┆┆89┆┄┆84┆ter device number┆e1┆ of the attached printer, if any. All ↓ ┆19┆┆89┆┄┄device numbers in the cluster must be unique. A printer ↓ ┆19┆┆89┆┄┄cannot be given device number zeo, as this indicates ↓ ┆19┆┆89┆┄┄that no printer is attached. Otherwise there are not ↓ ┆19┆┆89┆┄┄restictions on the assignment of device numbers.↲ ↲ ════════════════════════════════════════════════════════════════════════ ↓ ┆84┆A printer must be given a device number, even if it is ↓ ┆19┆┆89┆┄┄used for hard copy purpose only.↲ ↲ ┆84┆Every terminal must be configured with the printer ↓ ┆19┆┆89┆┄┄device number of its ┆a1┆hard copy printer┆a1┆┆e1┆. Seen from the ↓ ┆19┆┆89┆┄┄control unit there is not logical connection between the ↓ ┆19┆┆89┆┄┄display device of a terminal and the printer device that ↓ ┆19┆┆89┆┄┄may be attached to the terminal. The hard copy printer ↓ ┆19┆┆89┆┄┄of a terminal may be chosen freely among the printer ↓ ┆19┆┆89┆┄┄devices in the cluster. It is not even necessary only to ↓ ┆19┆┆89┆┄┄have one printer as hard copy printer, as it is possible ↓ ┆19┆┆89┆┄┄to define up to 16 ┆a1┆printer classes┆e1┆ each consisting of ↓ ┆19┆┆89┆┄┄several printers. Hard copy print from a terminal that ↓ ┆19┆┆89┆┄┄has specified a printer class as hard copy printer may ↓ ┆19┆┆89┆┄┄appear on any free printer belonging to the class.↲ ↲ ┆84┆Furthermore a printer device may be configured to accept ↓ ┆19┆┆89┆┄┄hard copy print from certain display devices only; and ↓ ┆19┆┆89┆┄┄any printer is configured to accept hard copy print ↓ ┆19┆┆89┆┄┄only, device print only, or a combination of both.↲ ↲ ┆84┆For more information on printer configurations, please ↓ ┆19┆┆89┆┄┄consult reference (1).↲ ↲ ↲ ┆b0┆┆a1┆7.2 Configuring a Terminal↲ ↲ ┆84┆The configuration is done by a configuration program, ↓ ┆19┆┆89┆┄┄that is down-line loaded from the Control Unit seperate┄↓ ┆19┆┆89┆┄┄ly.↲ ↲ ┆84┆The configurator works just like a 3270 oriented appli┄↓ ┆19┆┆89┆┄┄cation, i.e. data is entered by the operator by typing ↓ ┆19┆┆89┆┄┄into the input fields. The configurator provides a limit ↓ ┆19┆┆89┆┄┄check of the parameters and displays a warning if the ↓ ┆19┆┆89┆┄┄values exceed these limits. The parameters and the ↓ ┆19┆┆89┆┄┄valued values are discussed in subsection 7.2.2.↲ ↲ ┆84┆Having entered the configurator, the values of the ↓ ┆19┆┆89┆┄┄present parameters are displayed. The operator now ↓ ┆19┆┆89┆┄┄updates the desired parameters and terminates by pres┄↓ ┆19┆┆89┆┄┄sing the SEND key. If all parameter values are valid, ↓ ┆19┆┆89┆┄┄the non-volatile memory (NVM) is updated and the termi┄↓ ┆19┆┆89┆┄┄nal is reset automatically (i.e. the emulator is loaded ↓ ┆19┆┆89┆┄┄anew so that all parameters can take effect).↲ ↲ ┆84┆Often it is desirable to keep a printout of the current ↓ ┆19┆┆89┆┄┄parameter values. It is therefore recommended to fill in ↓ ┆19┆┆89┆┄┄the screen image shown in appendix B with these values ↓ ┆19┆┆89┆┄┄and to keep the description with the terminal.↲ ↲ ┆84┆If a printer is physically attached to the terminal, a ↓ ┆19┆┆89┆┄┄printout of the parameter values may be produced by the ↓ ┆19┆┆89┆┄┄following procedures. Note that the procedure to follow ↓ ┆19┆┆89┆┄┄depends on whether updating is required or not.↲ ↲ ════════════════════════════════════════════════════════════════════════ ↓ 1) enter configurator↲ ↲ 2) proceed according to:↲ ↲ ┆a1┆a) updating required b) no updating↲ ↲ - enter parameters - press PRINT key↲ - press SEND key↲ - invoke configurator again↲ - press PRINT key↲ ↲ 3) terminate by pressing SEND key.↲ ↲ ↲ ┆b0┆┆a1┆7.2.1 Initial Setting of Secondary Address↲ ↲ ┆84┆To make it possible to load the configurator program ↓ ┆19┆┆89┆┄┄from the Control Unit, the Secondary Address must be ↓ ┆19┆┆89┆┄┄initialized.↲ ↲ ┆84┆This is done by a simple built-in initialization pro┄↓ ┆19┆┆89┆┄┄gram.↲ ↲ ┆84┆In order to activate the program, the Display Station ↓ ┆19┆┆89┆┄┄must be reset by power-up or by pressure of the reset-↓ ┆19┆┆89┆┄┄button and the 'P'-key of the keyboard held down during ↓ ┆19┆┆89┆┄┄the self-test. However, the program will be activated ↓ ┆19┆┆89┆┄┄even if the 'P'-key is not pressed, if the value of the ↓ ┆19┆┆89┆┄┄LD-field of the NVM is equal to 3 (load from PROMs on ↓ ┆19┆┆89┆┄┄the MIC-board).↲ ↲ ┆84┆When activated, the program will display the text ↓ ┆19┆┆89┆┄┄'Secondary Address:' and wait for operator action.↲ ↲ ┆84┆Accepted inputs are digits (0-9), the ESC and SEND keys ↓ ┆19┆┆89┆┄┄and the combination of CTRL and CLEAR keys.↲ ↲ ┆84┆The secondary address must be given as a decimal number ↓ ┆19┆┆89┆┄┄in the range from zero to the maximum number of termi┄↓ ┆19┆┆89┆┄┄nals minus one. If a typing error is made, the pressure ↓ ┆19┆┆89┆┄┄of the ESC key will clear the input and enable new ↓ ┆19┆┆89┆┄┄input.
