Comments
These bits set the initial starting modem
rate for transmission.
Use the dedicated transmission
parameters if you need to change this for
specific receivers.
If a modem rate 14.4 kbps or slower is
selected, V.8 protocol should be disabled
manually.
Cross reference
V.8 protocol on/off - G3 switch 03, bit 2
These bits set the initial modem type for
9.6 and 7.2 kbps, if the initial modem rate
is set at these speeds.
Do not change the settings.
