Subjob is in monitor mode (PTY
only) .
Break on all characters
(terminals only) .
Truth in echoing mode
(terminals only) .
Maintenance DMR mode (KDP and
DTE devices only).
Bit mask for tape density,
where:
o standard
1 200
2 556
3 800
For densities of 1600 and
6250, IO.DEN=O (magtape only) .
This flag is obsolete. Use
TAPOP. to set tape density.
Semi-standard data mode
(DECtape devices only) .
Suppress echoing (terminals
only) .
DEC029 mode (card punch only) .
Super-image mode (card reader
only) .
write disk-pack headers (disk
only) .
Non-standard data mode
(DECtape devices only) .
Suppress form feeds (line
printers only) .
Read with no reread check
(magtape only) .
Obsolete (terminals only) .
Line editor mode (terminals
only) .
30 IO.SYN
31 IO.UWC
32-35 IO.MOD
Synchronous input.
Uses user word count. By default this bit is not
.set, and the monitor computes the amount of data
to be transmitted using the byte pointer in the
buffer header. If this flag is set, however, the
monitor uses the byte count. Meaningful for
output only.
Data mode. In general, modes 0-14 are considered
"buffered I/O modes" and modes 15-17 are "dump I/O
modes." The possible values for the data mode
(IO.MOD) in .OPMOD are:
Value Symbol Meaning
0 . IOASC ASCII mode (for any device
except display) .
1 . IOASL ASCII line mode (for any
device except display) .
2 . IOPIM Packed image mode (terminal
only) .
3 . IOBYT Byte mode (magtape device
only) .
