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: If the unit is in Modem Mode and the serial port is idle, the unit still 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). ‹ 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. To disconnect a connection using Modem Mode commands: 1. Ensure the following: ‹ 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. 2.

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:
If the unit is in Modem Mode and the serial port is idle, the unit still
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).
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.
To disconnect a connection using Modem Mode commands:
1. Ensure the following:
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.
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
.
