Description
Hook flash on-hook time. The amount of time in
20 millisecond units that the modem leaves the
telephone ON-HOOK while performing a hook-
flash according to the \ dial-string modifier.
Sets the highest line rate. This register specifies
the highest telephone-line data rate the modem
uses when connecting with a remote modem. If
the value of S37 is higher than the data rate the
modem supports, the modem attempts to connect
at its highest data rate.
The Communication Standard Options command
( B ) controls the modulation standards that are
allowed for telephone-line data rates that have
multiple options.
S37 specifies the telephone line data rate. The
modems may communicate with their terminals at
various data rates.
In case of conflict between the B option and the
S37 value, the S37 setting takes precedence.
Configure both modems identically to prevent
communication failures caused by incompatible
telephone line modulation standards.
