pin signal. This output can provide RS-232 flow
control, control the TX enable signal (for RS-485
or RS-422 operations), or set the default level
for the I/O line passing function.
By default, DO2 provides RS-232
(Clear-to-

exclusive connection. If MD = 2, the remote
modem will send a “Disconnect Request Packet”
to the base modem.
