Lantronix UDS1100 User Manual

7: 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 UDS1100s, 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).
