S-Registers
S37, Desired Line Connection Speed
Description
Specifies the desired line connection speed.
Notes
1. When the Nn command is issued or the S37 register value is modified, the +MS
command subparameters are updated to reflect the speed and modulation
specified by the S37 value (see
+MS, Select Modulation on page 1-34). For
example:
If N0 command is active, S37=10 updates the +MS command subparameters to
rMS=10,1,300,12000
If N1 command is active, S37=10 updates the +MS command subparameters to
rMS=10,0,12000,12000
2. S37 is not updated by the +MS command.
3. Use of the +MS command is recommended instead of the Nn and S37=x
commands. Nn and S37=x commands are supported for compatibility with existing
communication software.
Default: 0
Bits 0-4 Desired line connection speed. This is interlinked with the Fn command. If
an invalid number is entered, the number is accepted into the register, but
S37 behaves as if the default value was entered.
0 = Attempt automode connection. If N0 is active, connection is
attempted at the most recently sensed DTE speed (+MS command
settings are updated to the appropriate values). If N1 is active,
connection is attempted at the highest possible speed (+MS settings
are updated to 11,1,300,1440 to reflect V.32bis automode, 300 bps
minimum speed, and 14400 bps maximum speed) (default).
1-3 =Attempt to connect at 300 bps. F1 command
4 = Reserved.
5 = Attempt to connect at V.22 1200 bps. F4 command
6 = Attempt to connect at V.22 bis 2400 bps. F5 command
