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.
b. The DTE may disable automode operation (see <automode> below).
c. The DTE may constrain the range of modulations available by
specifying the lowest and highest rates (see <min_rate> and
<max_rate> below).
3. <automode> is an optional numeric value which enables or disables automatic
modulation negotiation using V.8 bis/V.8 or V.32 bis Annex A. The options are:
<automode> Option Selected
0 Automode disabled
1 Automode enabled using V.8 bis/V.8 or V.32
Annex A (Default)
