DESCRIPTION
Selects Answer mode in V.21 (transmit in high band,
receive in low band) or in V.23 mode, receive at1200 bit/s
and transmit at 75 bit/s.
Selects Originate mode in V.21 (transmit in low band,
receive in high band) or in V.23 mode, receive at 75 bit/s
and transmit at 1200 bit/s. If in V.23 and D2 of TR=1,
selects V.23 full duplex operation in 4-wire configuration.
