rst - Reset SCSI Bus
Type: SCSI Function
Syntax:
rst
<CR>
Purpose: Use
rst
if a device on the SCSI bus is not acting as expected
and, therefore, is preventing other SCSI activity from
occurring.
Remarks: This command causes the GPIB-SCSI-A to assert the SCSI
RST* signal for approximately 100
µ
sec. The assertion of
RST* for 25
µ
sec causes all devices on the SCSI to go to a
known, reset state.
If there is anything following
rst
, the command aborts and
returns an EARG indication.
See Also: Appendix D, Operation of the SCSI.
Example:
ibwrt (gpibscsia, "rst\n", 6);
/* The GPIB-SCSI-A asserts the SCSI RST*
* signal for a time during which all SCSI
* devices should go to a known, reset state.
