Modem Serial Port -
The modem serial port provides an RS-232 asynchronous serial DTE connection
via a DB9-M connector. See
appendix A
for pinout details. Use an appropriate serial cable to connect this
port to the DCE serial port of an analog modem to enable the Modemulator to manage PSTN
connections to or from remote analog modems. In gateway mode, this port is inactive.
