5-2 Tips on Configuring A Modem
Tips on Configuring A Modem
Here are some tips on configuring modems to work with PortServer TS 8/16:
•
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 PortServer TS 8/16 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 PortServer TS 8/16 as though they
were the host system’s own ports. It is an easy and efficient way for modems to use
PortServer TS 8/16 ports. For information on this option, see "Configuring Ports for
RealPort" on page 3-1.
