Modem (Emulation) Mode: In Modem Mode, the unit presents a modem interface
to the attached serial device. It accepts AT-style modem commands, and handles the
modem signals correctly.
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 UDS 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), or D7 (echo with 1-character response).
Note:
accepts network TCP connections to the serial port if Connect Mode is set to
C6 (no echo), D6 (echo with full verbose), or D7 (echo with 1-character
response).
To disconnect a connection using Modem Mode commands:
1. Ensure the following:
2. When the unit acknowledges with an OK to indicate that it is in command mode,
enter ATH and press Enter. The command is echoed if echo is enabled. ATH is
acknowledged by another OK.
If the unit is in Modem Mode, and the serial port is idle, the unit still
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 (no echo)
refers to the modem not sending an answer to the commands received (or
displaying what was typed).
Full Verbose: The unit echoes modem commands and responds to a
command with a message string.
1-Character Response: The unit echoes modem commands and responds
to a command with a single character response.
There must be a 1-second guardtime (no data traffic) before sending +++.
There must not be a break longer than 1 second between +s.
There must be another 1-second guardtime after the last + is sent.
