Lantronix XPress DR+ manual Message Meaning

Chapter 9: Setup Mode: Channel Configuration

Normally, there is a modem connected to a local PC and a modem connected to a remote machine. A user must dial from the local PC to the remote machine, accumulating phone charges for each connection. Modem Mode allows you to replace modems with XPress DR+ units, and to use an Ethernet connection instead of a phone call. By not having to change communications applications, you avoid potentially expensive phone calls.

To select Modem Mode, set the Connect Mode to C6 (no echo), D6 (echo with full verbose), D7 (echo with numeric response), CF (modem responses only, numeric response), or CE (modem responses only, full verbose).

Note: If the unit is in Modem Mode, and the serial port is idle, the unit can still accept network TCP connections to the serial port if Connect Mode is set to C6 (no echo), D6 (echo with full verbose), D7 (echo with numeric response, CF (modem responses only, numeric response), or CE (modem responses only, full verbose).

Without Echo		In Modem Mode, echo refers to the echo of all of the characters
		entered in command mode; it does not mean to echo data that is
		transferred. Quiet Mode (without echo) refers to the modem not
		sending an answer to the commands received (or displaying what
		was typed).
Data Echo & Modem		Full Verbose: The unit echoes modem commands and responds to
Response		a command with a message string shown in the table below.
		Numeric Response: The unit echoes modem commands and
		responds to a command with a numeric response.
Modem Responses		Full Verbose: The unit does not echo modem commands and
Only		responds to a command with a message string shown in the table

		and responds to a command with a numeric response.
