Modem Command

Modem Commands are used to control the media converter . You can use these commands to send and receive data.

A Modem Command is composed of 3 characters with prefix @.
These commands can be issued by sending the commands with the parameters defined for each command to COM port.

The media converter being connected via RS-232 cable explain the sent commands and parameters, and perform the requested process.
If returning response is set, the specified response string is returned.
