The external interfaces for IOC are the electrical
interfaces for devices and lines, where IOC in fact
implements the CAMPS external interface to devices/lines.
Interface descriptions are:
CAMPS ICDs ICD/004 through 8.
4.1.7.2 P̲a̲c̲k̲a̲g̲e̲ ̲I̲n̲t̲e̲r̲f̲a̲c̲e̲s̲
The interface for IOC can be divided into 4 main groups.
a) IOS Interfaces
b) Data transport interfaces (using IOS calls).
c) FORMAT HANDLER interfaces.
d) Control Interfaces for defining control parameters
within the IOC
4.1.7.2.1 I̲O̲S̲ ̲I̲n̲t̲e̲r̲f̲a̲c̲e̲s̲
The IOS interfaces are included here as background
information. For coding purposes please refer to DAMOS

The caller offers a file to another user. This means
that the user specified, may issue an "accept" command
and thereby get a file descriptor of the file. The
user will thus be able to access the file. In this
way it is possible for several users to exchange information
via a file without a name.
The access rights of the user who accepts the file,
depends on whether or not the user who "offers" the
file are allowed to protect the file:
- "offerer" has protect right:
"accepter" gets the access rights which are the
union of:
1) the rights the "accepter" already has
2) the intersection of the "offered" and the rights
the "offerer" has.

The data transport to/from a terminal is exercised
by calling the IOS procedures.
APPEND BYTES
READ BYTES
The buffer content, which is a logical contiguous byte
string either specified to the IOS or returned from
the IOS is formatted as specified below.
The start byte identifies the start of a record. It
may also occur in data, but only when flagged as control
characters.
The Byte Count gives the length of Data (so that total
length is bytecount + 3). The maximum length is dependent
on the interfaced line.
The flag byte give the type of the data transferred.
It may be a line or a field or a string of control
characters. If a line of text has not been terminated
in a normal way the Flag Byte indicates this. Three
ways of abnormal termination may be identified.
a) The line is not terminated by the normal character
sequence, but by a different sequence (control
characters). The line is defined as data and a
new record is initiated (control type).
b) The line length exceeds the predefined length.
The line is defined as data and a new record is
initiated.
c) An unexpected V24 line status change or a key on/off
or a timeout (more than predefined time interval
between two characters) detected. The current record
is terminated as a data record and the IO request
is terminated with an error code indicating the
reason for termination.
The general layout of the buffer is presented in figure
4.1.7.2.2-1.

records will be type 0, 1 or 4 as shown in figure 4.1.6.2.2.2-2.
If the application has no open connection to the terminal
an error code is returned.
The conventions for ITA 5 input processing for PTR
are as follows:
Characters are normally collected in type 1 records,
where either the sequence "CR, CR, LF" or "CR, LF"
is used as separator.
Where more than 69 characters have been received without
this termination of line, they are collected in a type
0 record and a new count is initiated. Occurrence of
any other control characters than above line termination
leads to an immediate recording of already received
characters into a type 0 and collection of control
characters in type 4 (except superfluous SI,SO which
are delete). If a control sequence is longer than 69
characters it will be collected in a type 4 record
and new record will start. If normal characters (1
or more) are received, record type 4 is terminated
and a type 0 or 1 started.
An application input is terminated on:
Message End received, Message Start received (except
just after Message End, Break of 30 seconds (except
just after Message End).
An I/O is further terminated on device failure.
If no application IO request is present, characters
received from the PTR are lost.
For lines operating in ITA 2, the same rules apply,
except that Shift In and Shift Out characters are allowed
to determine the meaning of next characters. Superfluous
Letter shift or Figure shift are deleted as described
above.

The TRC and P to P are interfaced by use of the IOS
APPEND BYTES and READ BYTES with record types identical
to the ones shown for PTP/PTR in section 4.1.6.2.2.2.
4.1.7.2.2.4 O̲C̲R̲ ̲D̲a̲t̲a̲ ̲I̲n̲t̲e̲r̲f̲a̲c̲e̲
The OCR is interfaced by use of IOS READ BYTES. Received
records will be type 0, 1, 4, 5, or 6 as shown in figure
4.1.6.2.2.4-1. If the application has no open connection
an error code is returned.
The conventions for ITA 5 input processing for OCR
are as follows:
Characters are normally collected in type 1 records,
where either the sequence "CR, CR, LF" or "CR, LF"
is used as separator. When more than 69 characters
have been received without this termination of line,
they are collected in a type 0 record and a new count
initiated. Occurence of any other control character
(-sequence) than above line termination leads to an
immediate recording of already received info in type
0 and collection of control chars in type 4. If a control
charseq. is longer than 69 it is divided into several
of max length 69. The first occurence of a non-control
character terminates the type 4 record and starts building
a type 0 or 1. Control characters ETB are not returned
to the application.

The input is obtained by use of READ BYTES. Received
records will be type 0, 1, 4, 5 or 6, where 0, 1 and
4 are resulting from decoding of message text and 5
and 6 are indicating start and end of message respectively.
An error is returned if the application has no open
connection to the terminal or if a fatal error has
occured on the link.
The input conversion is shown in fig. 4.1.7.2.2.5.
Output is performed by using IOS APPEND BYTES. Allowed
record types are 0, 1, 4, 5 and 6. The output conversion
is the inverse of the input conversion. An error code
will be returned if the record length is not identical
to the one specified.
The interface to NICS ̲TARE is implemented via 3 connections,
one for Data (input+output), one for acknowledges (output
only) and one for LCB!s (input+output).

records will be of type 0, 1, 4, 5 or 6, where 0, 1
and 4 are are resulting from decoding of the message
text and 5 and 6 are indicating start and end of message
respectively.
An error is returned if the application has no open
connection to the terminal or if the message control
field of the protocol is in error (i.e. blocks out
of sequence, precedence and type changed). Message
control field errors following blocks are ignored.
The input conversion is shown in fig. 4.1.7.2.2.6.
Output is performed by using the IOS APPEND BYTES.
Allowed record type are 0, 1, 4, 5 and 6. The output
conversion is the inverse of the input conversion.
An error code will be returned to the requestor (e.g.
THP) if the record length is not identical to the one
specified.

The FORMAT HANDLER is a set of monitor procedures called
via the System Call Monitor.
For each of the below specified interface routines,
the application may issue all system call monitor functions:
INIT, WAIT, CANCEL, WAIT NEXT.
The interface routines can be grouped into two major
groups:
- Process oriented interface.
- VDU split oriented interface.
Format Handler Definitions, Adat. - P3 extensions
1) Any number of consecutive Format Lines may be defined
as a line group.
2) A Format Line can only belong to one line group.
3) A Linegroup is consecutive to another Linegroup
if the Format Line number of the first line of
the Linegroup is one superior to the last Format
Line of the other Linegroup.
4) A consecutive set of Format Lines are consecutive
to a Linegroup if the last Format Line in the Linegroup
is one below the first Format-line in the set.
5) Similar for Format Lines following a Linegroup.
6) A Linegroup is defined as a set of consecutive
Linegroups and/or Format Lines.
7) A Linegroup may only belong to one other Linegroup.
8) A Format Line/Linegroup may be repeated or deleted
as long as any repetition has not taken place in
higher levels of Linegroup definitions.
9) A repetition of a Linegroup copies exactly the
Format layout for the Linegroup of the moment of
the repetition request with all fields in the repeated
area empty.

The field handling functions are performing input and
output of fields.
Fields are transferred from / to the application buffers.
The interface is based on a definition of a field buffer
and a field list buffer as shown in fig. 4.1.7.2.3-1.
For output, the fields are taken as specified in the
field list, assuming that the fields are sequenced
in the Buffer as defined in the field list. The Buffer
is the consecutive byte string defined by buffer 1,
buffer 2 and buffer 3.
For input, the field content is put into the Buffer
defined as above and the field list is constructed
reflecting the content of the Buffer.
The layout of the field list is shown in fig. 4.1.7.2.3-2
and the Buffer in fig. 4.1.7.2.3-3.
The Number of bytes is the byte length of the transfer
(i.e. the example the length of record 1 + record 2
+ record 3 + record 4 but excluding the unused part
of Buffer 2).

The PRINTER FORMAT HANDLER is a set of monitor procedures
called via the System Call Monitor.
For each of the below specified interface routines,
the application may issue all system call monitor functions:
INIT, WAIT, CANCEL, WAIT NEXT.
The interface routines can be grouped into two major
groups:
- Process oriented interface.
- Printer split oriented interface.
Printer Format Handler Definitions, Adat. - P3 extensions
1) Any number of consecutive Format Lines may be defined
as a line group.
2) A Format Line can only belong to one line group.
3) A Linegroup is consecutive to another Linegroup
if the Format Line number of the first line of
the Linegroup is one superior to the last Format
Line of the other Linegroup.
4) A consecutive set of Format Lines are consecutive
to a Linegroup if the last Format Line in the Linegroup
is one below the first Format-line in the set.
5) Similar for Format Lines following a Linegroup.
6) A Linegroup is defined as a set of consecutive
Linegroups and/or Format Lines.
7) A Linegroup may only belong to one other Linegroup.
8) A Format Line/Linegroup may be repeated or deleted
as long as any repetition has not taken place in
higher levels of Linegroup definitions.
9) A repetition of a Linegroup copies exactly the
Format layout for the Linegroup of the moment of
the repetition request with all fields in the repeated
area empty.

Initialization. The first call for handling a split
(printer) defines the format area to be used for this
interface. The reserved format area remains reserved,
but it is possible to handle a different split via
the interface. To handle a different split, the Remove

Init Printer.
Input: Maximum size of control tables ever to be handled

Output: Done + interface number (IFCB index).
The interface number (IFCB index) must be supplied
for all access defined below because it eventually
defines the actual format file used and the actual

one split and should only be called once, whereas format

Fields are transferred from the application buffers.
The interface is based on a definition of a field buffer
and a field list buffer as shown in fig. 4.1.7.2.3-1.
The fields are taken as specified in the field list,
assuming that the fields are sequenced in the Buffer
as defined in the field list merged into the format
specified by Get ̲Format and transferred to the printer
(split).
The Buffer is the consecutive byte string defined by
buffer 1, buffer 2 and buffer 3.
The layout of the field list is shown in fig. 4.1.7.2.3-2
and the Buffer in fig. 4.1.7.2.3-3.
The Number of bytes is the byte length of the transfer
(i.e. the example the length of record 1 + record 2
+ record 3 + record 4 but excluding the unused part
of Buffer 2).
The transforming of fields including the format is
terminated by Output ̲Format.
