Tips on Configuring A Modem

Here are some tips on configuring modems to work with Digi One/PortServer TS 2/4:

Configure the modem so that DCD goes high when it receives an incoming connection request.

Configure the modem to answer an incoming call only when DTR is high, and to drop the line when DTR goes low.

For bidirectional connections, it is advisable to configure the non-volatile parameters in the modem for incoming calls. Also configure the modem to reset to these parameters when DTR is dropped.

Configure the modem to lock the serial line speed at the highest baud rate the modem will accept for reliable data transfer because Digi One/PortServer TS 2/4 cannot switch the baud rate of the serial line on a per call basis without reconfiguration.

Note: You may want to consider connecting modems using RealPort, a feature that allows network-based host systems to use the ports of the Digi One/PortServer TS 2/4 as though they were the host system’s own ports. It is an easy and efficient way for modems to use Digi One/PortServer TS 2/4 ports. For information on this option, see "Configuring Ports for RealPort" on page 3-1.
