substitution of the form feed character in the output
stream. When the value is true, the device driver does not
substitute the form feed character when it is encountered
in the carriage control of terminals. When the value is
false, the form feed character is replaced.
The behavior of this item varies with the connection type
(for example, DTC direct connect, PAD, or Telnet/iX). This

| 13306 | End of Tape (B) Get: Yes; Put: No; Verify: No;
Release 4.0
If it returns true, the tape is positioned at the end of
tape (EOT). |
| 13307 | Immediate Report (B) Get: Yes; Put: No; Verify: No;
Release 4.0
Returns true when the tape device is operating in
immediate report mode. This means that the device will
buffer data until it has enough data to flush to tape.
This is the recommended mode of operation. |
| 13308 | Track Error (B) Get: Yes; Put: No; Verify: No;
Release 4.0
If it returns true, a single track was found in
error. |
| 13309 | Unit Online (B) Get: Yes; Put: No; Verify: No;
Release 4.0
If it returns true, the tape drive is online. |
| 13310 | Write Protect (B) Get: Yes; Put: No; Verify: No;
Release 4.0
If it returns true, it indicates that the tape is write
protected. |
| 13311 | Rewind (No value needed) Get: No; Put: Yes; Verify: No;
Release 4.0
Rewinds the tape to the beginning of tape. NOTE: The tape
unit is left online at the end of the rewind. |
| 13312 | Rewind Offline(No value needed) Get: No; Put: Yes;
Verify: No; Release 4.0
Rewinds tape to the beginning of tape and puts it offline.
The tape remains in the drive. |
| 13313 | Write Tape Mark (No value needed) Get: No; Put: Yes;
Verify: No; Release 4.0
Causes one tape mark to be written to tape. Writing tape
marks past end-of-tape is permitted. |
| 13314 | Forward File (No value needed) Get: No; Put: Yes;
Verify: No; Release 4.0
Moves the tape forward over the next tape mark but before
the next record. |
| 13315 | Backward File (No value needed) Get: No; Put: Yes;
Verify: No; Release 4.0
Moves the tape backward over the previous file mark that
is encountered or to the beginning of tape if there is no
file mark. The position is immediately in front of the
file mark. |
| 13316 | Forward Record (No value needed) Get: No; Put: Yes;
Verify: No; Release 4.0
Moves the tape forward to the beginning of the next
record. |
| 13317 | Backward Record (No value needed) Get: No; Put: Yes;
Verify: No; Release 4.0
Moves the tape backward to the beginning of the previous
record. If previously positioned at the end of a record,
the new position is at the beginning of that
record. |
| 13318 | Gap Tape (No value needed) Get: No; Put: Yes; Verify:
No; Release 4.0
Moves the tape forward and erases approximately 3.5 inch
of tape. For DDS drives, this does nothing. |
| 13319 | Set Density (I32) Get: No; Put: Yes; Verify: No;
Release 4.0
Set the density that a tape will be written at
| 0 | 6250 BPI for HP 7978 & 7980 |
| 1 | 1600 BPI for HP 7974, 7978, 7979, all 7980s, and all DDS |
| 2 | 800 BPI for HP 7974 and some 7978, 7979, and 7980 |
| 3 | compressed for HP 7980XC and 7980SX |
| 4 | no compression for HP 7980XC and 7980SX |
Density can only be set when a tape is at load point. The
density change can vary at the point in which it is
displayed. Some devices reflect the change immediately
while other devices reflect the density change as the
first record is being written. This behavior is device
dependent and is not guaranteed to be consistent across
all tape drives. |
| 13320 | Set Start/Stop (No value needed) Get: No; Put: Yes;
Verify: No; Release 4.0
Set the HP 7974 to operate in a start/stop mode (50 ipd).
This command does nothing on all other devices. |
| 13321 | Set Streaming (No value needed) Get: No; Put: Yes;
Verify: No; Release 4.0
Set the HP 7974 to operate in a streaming mode. If data is
not available to continually write to tape, the drive
stops the tape. The drive then repositions itself before
it can begin writing again. This item does nothing on all
other devices as they are always in this mode. |
| 13322 | Enable/disable Immediate Report (No value) Get: No;
Put: Yes; Verify: No; Release 4.0
With immediate report enabled, the device queues up
requests. Performance improves when immediate report is
enabled. |
| 13325 | Enable/Disable Data Compression (B) Get: No; Put: yes;
Verify: no; Release 5.0
Enable or disable data compression on a HPC1504B or
HPC1521B DDS drive. This item is not supported on other
DDS devices and all 1/2in tapes. The data compression
setting will remain in effect until reset via AIFDEVICEPUT
or the DEVCTRL.MPEXL.TELESUP program. |
| 13326 | Remote Load (No value needed) Get: No; Put: Yes; Verify:
No; Release 4.0
This loads a tape to BOT but does not place the drive
online. Not valid for the HP 7974 or HP 7978A. |
| 13327 | Remote Unload (No value needed) Get: No; Put: Yes;
Verify: No; Release 4.0
This unloads a tape and either opens the door (for all
7980s) or ejects the tape (for all DDS). Not valid for the
HP 7974 or HP 7978A. |
| 13328 | Remote Online (No value needed) Get: No; Put: Yes;
Verify: No; Release 4.0
This places the drive online. If this item is done to a
drive with no tape, or the door is open (7980), the
request does not complete until a tape is inserted or the
door is closed. Not valid for the HP 7974, HP
7978A/B. |
| 13329 | Enable/Disable Eject (B) Get: No; Put: Yes; Verify: No;
Release 5.0
This allows both 1/2in and DDS tape devices to be
dynamicaly configured to eject the media following an
application rewind/offline or close. This item is not
supported on HP 7974, 7978, 7979, 7980, 7980XC, and HP4280
devices. This behavior is device dependent and is not
guaranteed to be consistent across all tape
drives. |
