Description
Not Used
Not used
Sets the length of time, in seconds,
that the modem conducts a test
(commanded by &Tn) before return-
ing to the command mode. If this
register value is zero, the test will
not automatically terminate; the test
must be terminated from the com-
mand mode by issuing and &T0 or H
command. When S18 is non-zero,
the modem returns the OK mes-
sage upon test termination.
