S36 sets the time between when DTR goes inactive and when the modem goes off-hook. The DTR busy-out
feature is disabled when S36 is set to 0.
Normally, when the DTR signal from the computer goes inactive, the modem goes on-hook after a time
that is set by S25. If S36
is set for a non-zero time, the modem then waits for the time set by S36; if DTR
has not gone active again in that time, the modem goes off-hook, causing a busy signal for callers. The
busy-out state ends when DTR goes active again.
S37 DTR Busy-In Time
Unit: 1 second
Range: 0–255
Default: 5
S37 sets the time between when DTR goes active and when the modem goes on-hook, if S36 has caused it
to go off-hook.
S43 Force V.34 Connect Speed
Unit: N/A
Range: 0, 33, 31, 28, 26, 24, 21, 19, 16, 14, 12, 96, or 48
Default: 0 (disabled)
S43 forces the modem to attempt to connect at a fixed speed in V.34 mode. The two-digit value
corresponds to the first two digits of the speed (S43=21 sets the connect speed to 21.6K bps, S43=96 sets
it to 9600 bps, etc.). The factory default of zero disables this feature and allows the modem to establish the
best speed for the conditions.
Note: The $MB command overrides S43 if the $MB command is set to a speed other than 33,600 bps.
S48 Maximum V.34 Connect Speed
Unit: N/A
Range: 0, 33, 31, 28, 26, 24, 21, 19, 16, 14, 12, 96, or 48
Default: 0 (disabled)
S48 sets the maximum speed in bps at which the modem can attempt to connect in V.34 mode. The two-
digit value corresponds to the first two digits of the speed (S48=26 sets the maximum connect speed to
26.4K bps, S48=48 sets it to 4800 bps, etc.). This register allows you to set lower speeds for line conditions
that will not support higher V.34 speeds such as 33.6K, 31.2K, 28K, 26.4K, or 24K. The factory default of
zero disables this feature and allows the modem to establish the best speed for the conditions (in effect, it
sets a maximum connection attempt of 33.6K).
S94 Out-of-Service Time
Unit: 1 second
Range: 0–254, 255
Default: 45
S94 sets the maximum number of seconds, from 0 through 254, that the modem remains out of service
when the *H1 command is active. A value of 255 causes the modem to remain out of service indefinitely.
However, if the modem receives an enable command from the management program while the modem is
out of service, the modem returns to service immediately, before the S94 time expires.
