Carrier Detect/DSR Forcing -- "DSR"
(Asynchronous/Synchronous Mode/Dial-Up/Leased Line)
Some terminals react in unusual ways to the toggling of the Carrier Detect (CD - RS-232C/V.24 pin
6) signals. The most common symptom is that the modem does not respond to commands, or does
not echo characters. In these cases, it is advisable to force these two signals On in order for the
terminal to communicate properly with the modem in Command mode. This is done by setting DIP-
Switch #15 DOWN. With DIP-Switch #15 in the UP position, both CD and DSR will be either on or off,
depending on the On-Line status.
CD and DSR normal = Switch #15 UP
CD and DSR forced On = Switch #15 DOWN
Factory Default Setting = UP
Switch #16
