V.33 operation is available on the Modem at speeds of 12,000 and 14,400 bps.
V.33 leased-line operation provides compatibility with V.33 modems
(synchronous operation only).

connected modems must be set for V.33 operation.

immediately begins the training sequence, meaning it is ready to handshake
with the originate modem.

unit, the EIA status screen is present. This screen looks like the one shown
