S-Registers
C-24
Register: S18
Description: The value in this S-register establishes the duration of
diagnostic tests initiated by the &T command.
Range of Values: Value may be 000 through 255 seconds. The
factory-default value is 0.
Storable: yes
Comments: Any locally initialized test in progress is automatically
terminated when the time specified in S-register S18
has elapsed. If S-register S18 is set to 0, a test initiated
by the &T command must be terminated manually.
Issuing the &T0 command terminates any locally
initiated test immediately, regardless of the value in
S-register S18.
See Also: The &T command on page A-26, and Appendix D for
information about performing loopback tests.
Register: S19 — not used.
Register: S20 — not used.
