Description
S12 Escape Guard Time. Register sets the value (in 20-millisecond increments) for
the required pause before and after the escape sequence is issued. The guard
time prevents the modem from interpreting data as the escape sequence
characters.
Enter a value from 0–255 in 20-millisecond increments. The factory setting of
50 equals 1000 milliseconds or one second.

DTE Dialer
S14 Asymmetric Rate Mode. Register determines whether VF rates for transmitting
and receiving are identical when using V.34 modulation on a dial line. The
factory setting is Enable.

Dial Line
S15 Asymmetric Rate Mode. Register determines whether VF rates for transmitting
and receiving are identical when using V.34 modulation on a leased line. The

S18 Test Timeout. Register sets the duration (in seconds) for the modem tests.
This automatically cancels any test in progress after the time of this register
expires. Any test can be manually canceled by issuing the escape sequence
(+++) followed by the &T0 command.

3 = 3200H
4 = 3000L
5 = 3000H
6 = 2800L
7 = 2800H
