This manual describes the use of magnetic tape stations connected to ↓
RC8000 through IDA801 (IDA - Intelligent Device Adapter) (ref. 1).↲
↲
The tape stations supported are RC3715 (ref. 2), RC8343 (ref. 3) and ↓
RC8344 (ref. 4).↲
↲
The tape stations supported are ECMA, ISO, ANSI and IBM format compatible ↓
(see Appendix F).↲

┆a1┆2.╞ COMMUNICATION PROTOCOL┆e1┆↲
↲
The RC8000/IDA Magnetic Tape Process is an RC8000 external process (ref. ↓
5, section 3.3), representing a magnetic tape document.↲
↲
The Magnetic Tape Process operates in three states:↲
↲
╞ ╞ 1.╞ no_document_mounted↲
╞ ╞ 2.╞ unidentified_document_mounted↲
╞ ╞ 3.╞ identified_document_mounted↲
↲
The initial state of the process is ┆a1┆no document mounted┆e1┆. When a tape is ↓
mounted and the device is switched to ┆a1┆online┆e1┆ (remote), the process state ↓
will be changed to ┆a1┆unidentified document mounted┆e1┆. Internal processes ↓
which have sent a message to the ┆a1┆remoter process┆e1┆ (ref. 6), will now re┄↓
ceive an answer notifying them of the event (this facility will normally ↓
only be of interest to operating systems).↲
↲
When a device is named by means of the monitor procedure ┆a1┆create peri┄↓
┆19┆┄┄┆84┆pheral pro┄cess┆e1┆, the process state becomes ┆a1┆iden┄ti┄fied docu┄ment moun┄ted.┆e1┆↲
↲
Operations can be initiated in all process states by an internal process ↓
that has ┆a1┆initialized┆e1┆ or ┆a1┆reserved┆e1┆ the device. These monitor procedures do ↓
not change the process state.↲
↲
The device is sensed before each operation. If the status word indicates ↓
that the device is ┆a1┆offline┆e1┆ (local), the name of the process is removed, ↓
and the present reservation (if any) is cancelled. The process state is ↓
changed to ┆a1┆no document mounted┆e1┆ and all pending and future messages will ↓
be answered with result = 5: ┆a1┆receiver does not exist┆e1┆.↲

┆84┆┆a1┆Halfwords transferred┆e1┆ (hw transferred) and ┆a1┆Characters transferred┆e1┆ (chars ↓
transferred) are used to report the amount of data actually transferred ↓
┆8c┆┆83┆┆c8┆↓
in operations involving data transfers to or from a data storage area in ↓
RC8000. Chars transferred is the controller's count of characters ↓
actually written on or read from the tape. Hw trans┄fer┄red is a calculated ↓
value:↲
╞ ╞ hw transferred:= (chars transferred + 2) // 3 * 2↲
↲
┆84┆Both values will equal zero after operations which do not involve such ↓
data transfers, i.e. if the operation definition does not require a data ↓
storage area to be stated.↲
↲
┆a1┆File and Block Number┆e1┆↲
↲
All answers from magnetic tape stations contain a file and block number ↓
defining the position of the tape after the operation.↲
↲
These simple file and block numbers are supplied by the IDA controller ↓
and based solely on keeping track of operations performed and status bits ↓
sensed. There is no check against file and block numbers in labels and ↓
data blocks.↲
↲
The IDA controller internally uses one more number, 'old block number', ↓
to keep track of the block numbers. Both the file number and the two ↓
block numbers are initialized to 0 when load point (the BOT-marker on ↓
the tape) is sensed. When the on/off-line status of the tape station ↓
changes, this will result in rewinding of the tape, resulting in initia┄↓
lizing the file number and block numbers to 0.↲
↲
When a file mark is output or when a file mark is sensed during a for┄ward ↓
move or read operation, the file number is increased by one, 'old block ↓
number' is set to 'block number' and 'block number' is set to zero.↲
↲
When a file mark is sensed after a backward opera┄tion, the file number is ↓
decreased by one, 'block number' is set to 'old block number' and 'old ↓
block number' is set to -1. If now 'block number' = -1, a backspace file ↓
operation is performed, followed with upspace file and one backspace ↓
file operation. Now 'block number' will be defined.↲
↲
┆8c┆┆83┆┆bc┆↓
The block number is increased by one when a block is input, output, or ↓
upspaced. Partial blocks and other blocks with errors count as normal ↓
blocks. The block number is decreased by one when a block is backspaced.↲
↲
┆a1┆Detailed Status┆e1┆ are 8 bytes of additional status information as defined ↓
in Appendix C. This information is not available from RC3715, in which ↓
case all 8 bytes (three words) will equal zero. This status is only ↓
available after the operations sense and set mode.↲

┆a1┆B.╞ STATUS WORD↲
↲
↲
The status word in an answer (see 4) is a bit pattern used to re┄port ↓
errors as well as to report certain conditions in the station state as ↓
described below. Only the 10 most significant bits (bit 0-9) in the word ↓
are used. The remaining bits will have the value zero.↲
↲
┆a1┆bit 0╞ Intervention↲
↲
┆84┆Indicates the device went off-line ┆a1┆during┆e1┆ the operation. If the device ↓
was off-line before the operation, this would be indicated as stated in ↓
section 2: the answer would be returned with result = 5 (receiver does ↓
not exist).↲
↲
┆a1┆bit 1╞ Parity Error↲
↲
Indicates an unrecoverable error in the data on the tape or some sort of ↓
hardware malfunction. On RC8343 and RC8344, the 'detailed status' (see ↓
Appendix C) obtained by executing the operation 'sense' (see 3.2) give ↓
further information on the nature of the error. On RC8344, the 'extended ↓
status information' (see Appendix D) obtained by exe┄cuting the operation ↓
'extended sense' (see 3.9) will give a very precise description of the ↓
error.↲
↲
However, parity error can also indicates "soft" errors:↲
↲
After 'input' (3.3):╞ ┆84┆Neither a data block, nor a file mark, was found ↓
┆19┆┆98┆┄┄within a certain time (corresponding to about 10 ↓

delivered from or required by the tape station.↲

┆a1┆bit 4╞ Block Length Error↲
