COMSPHERE 392xPlus Modems
S-Register
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.
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.
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
factory setting is Enable.
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.
Enter a value from 0–255 seconds. A value of 0 disables this register. The
factory setting is Disable (0).
S21 V34 Symbol Rate. Register sets the symbol (or baud) rate to be used when
operating with V.34 modulation on either dial or leased lines. The factory
setting is Automatic, which is the only setting compliant with the V.34
specification. It is recommended that you do not change it.
Register has the following values:
0 = Automatic
1 = 3429L
2 = 3200L
3 = 3200H
4 = 3000L
5 = 3000H
6 = 2800L
7 = 2800H
8 = 2743L
9 = 2743H
10 = 2400L
11 = 2400H
12 = 3429H
S22 Sync DTE CRC. Register determines whether the CRC of the DTE frame is
transmitted from modem to modem.
Register has the following values:
0 = Ignore
1 = CRC16
The factory setting is Ignore.
