Table 10 - Manual Connection Address Example
Command String Result if remote IP is 129.1.2.3 and remote port is 1234
C121.2.4.5/1 Complete override; connection is started with host 121.2.4.5, port 1
C5 Connect to 129.1.2.5, port 1234
C28.10/12 Connect to 129.1.28.10, port 12
Autostart (Automatic Connection): If autostart is enabled, the unit automatically connects
to the remote IP address and remote port specified.
Datagram Type: When selecting this option, you will be prompted for the Datagram type.
Enter 01 for directed or broadcast UDP.
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 device
servers, and to use an Ethernet connection instead of a phone call, without having to change
communications applications and make 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 can still accept
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).
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 (no echo) refers to the modem not
sending an answer to the commands received (or displaying what was typed).
To disconnect a connection using Modem Mode commands:
There must be 1-second guardtime (no data traffic) before sending +++. 
There must not be a break longer that 1 second between +s.
There must be another 1-second guardtime after the last + is sent.
The unit acknowledges with an OK to indicate that it is in command mode.
Enter ATH and press Enter. It is echoed if echo is enabled. ATH is acknowledged
by another OK.
