### Tips on Configuring Your Modem

Use this topic for tips on configuring your modem to work with Digi One RealPort and PortServer TS. See your modem manual for information on modem requirements.

#### Tips

Configure the modem:

- So that DCD goes high when it receives an incoming connection request.
- To answer an incoming call only when DTR is high, and to drop the line when DTR goes low.
- To lock the serial line speed at the highest baud rate the modem will accept for reliable data transfer because the Digi device cannot switch the baud rate of the serial line on a per call basis without reconfiguration.
- So that DCD is off when the modem is not connected
- So that the modem does not answer a call when DTR is low
- So that the modem hangs up when DTR is dropped
