Chapter 4 – Using the MultiModem iSMS Web Interface
41 MultiModem® iSMS System Administrator’s Guide
TCP Connection
The TCP Connection feature is a per modem port feature that provides direct AT Command access to the modem's serial
interface for troubleshooting purposes only. When you open a TCP socket on the defined TCP port number (e.g. 5000),
the modem is no longer available to the unit's send and receive queues. Events that occur while the socket is open to the
modem do not get logged by the system (i.e. SMS messages received by the modem are not logged in the system nor
delivered through the Receive API process). It is recommended that you disable this feature after you have setup and
tested the system.
TCP Connection
Enable or Disable the TCP Connection by clicking the appropriate radio button. Default: Enable
TCP Connection Port
The TCP port number on which the MultiModem iSMS is listening. Ensure each cellular modem port in the MultiModem
iSMS is listening on a different TCP port number.

of an SF800.
