EtherPath User’s Guide
4
EtherPath will connect to any port number under user control with
either hardware (pin6) dialing or AT dialing.
By using the "AT Dial" commands, the connected device can direct
the EtherPath to connect to multiple remote devices, one at a time.
Other Features
Automatic Connection
When used in Client/Server mode, the “Client” EtherPath will
automatically establish a connection to the “Server” EtherPath on
power-up, or under the control of an RS-232 control signal.
AT Commands
The EtherPath responds to most common AT commands when in
the Client mode. Commands are listed in the Appendix.
Connection Recovery
The EtherPath uses a proprietary protocol to ensure the client/server
session always exists on TCP/IP. When data hasn't been transferred
through the connection for some time, the EtherPath will
communicate with the other device (either EtherPath or PC) to
ensure that the connection is still open.
If there is no response, the device will reset to the initial state, and
attempt to reconnect.
Also, if the RS-232 link is broken, it will be reconnected
automatically if possible (when in Hardware-connect mode).
This operation is described in the Appendix.
Protocol Conversion
The RS-232 device at the client end and the device at the server end
of a link do not have to use the same communications protocols on
