COURIER HIGH SPEED MODEMS

External Modem Set Up 2-5

NOTE: If you have built your own RS-232 cable and it does

not support the Data Terminal Ready (DTR) signal, set DIP

switch 1 ON, for DTR override. The override causes the

modem to operate as if the DTR signal were always ON,

and enables the modem to accept commands. Most

purchased communications software, however, requires

“normal” DTR.

8. The final step is to connect the modem to the computer's or

terminal's serial port with the RS-232 cable. Attach the

appropriate connectors to the modem and to the serial port.
