When you want to switch from modem to voice communication, simply lift up the
handsets of both sides and press the ENTER key while the blinking cursor is on the
H or Hang Up. The LCD display will show DISCONNECTING ? to ask for a confir-
mation. Press ENTER again and the modem will change from data to voice commu-
nication. When both sides wish to return to data communication, one side should
press O while the other side presses A (as explained previously). This operation will
reinitiate the modem handshaking and enable data communication.
For the non-LCD model, use the VOICE/DATA toggle switch for data/voice switching
and use the ORG/ANS switch to select originate mode or answer mode on-line. For
the Omni model, the AT*Mn command or S14b0 will decide originate or answer
mode on a manual connection. Whenever your modem establishes a connection
with another modem, one of the modems must be in answer mode and the other
modem in originate mode or a connection is not possible.
Repeat Last Dial
Access R (Repeat last dial) by pressing the left or right arrow key and the ENTER key.
Before a connection is made, any key pressed from the front panel or terminal key-
board will abort the redial operation.
Auto Answer

number of rings until the modem automatically answers. Setting this value to zero
disables auto answer.
