Subparameter Definitions
1. <mod> = A decimal number which specifies the preferred
modulation
(automode enabled) or the modulation (automode disabled) to
use in originating
or answering a connection. The options are:
<mod> Modulation Possible Rates (bps) 1

Notes:
1. See optional <automode>, <min_rate>, and <max_rate>
subparameters.
2. For V.23, originating modes transmit at 75 bps and receive at
1200 bps; answering modes transmit at 1200 bps and receive at 75 bps. The rate
is always specified as 1200 bps.
The modem may also automatically switch to another modulation
(automode), subject to the following constraints:
a. The modem may not be able to automatically switch from the current
modulation (specified by <mod>) to some other modulation. For example, there
is no standard way to automode from Bell 103 to V.23.
