OnCell G2111/G2151I Series AT Command Set

AT Command Set Introduction
The OnCell G2111/G2151I Series modem supports the V.25ter AT command set. The “AT” prefix (also known
as the Attention Code) signals the modem that one or more commands are to follow. The AT command set is
an industry-standard language that is used to communicate with modems. The OnCell G2111/G2151I Series
modem is always either in command mode or in on-line mode. When first powered up, the modem will enter
command mode. The modem will only accept commands when it is in command mode. Commands that are
received when the modem is in on-line mode are treated as data, not as commands. Commands may be
entered from terminal software such as Windows HyperTerminal, or Moxa PComm Lite Terminal Emulator.
Settings made with AT commands are automatically reused by the modem until another command is received
to change the settings, or the modem is turned off.
All but two of the commands must begin with the characters AT. The two exceptions are the escape sequence
(+++), and the repeat command (A/). The command line prefix (letters AT) and the command sequences that
follow can be entered in upper case or lower case, but the cases must not be mixed. More than one command
can be typed on one line, and commands can be separated by spaces to make them easier to read. The
spaces are ignored by the modem’s command interpreter. The command line buffer accepts up to 39
characters including, “A” and “T”. Spaces, carriage returns, and line feed characters are not placed in the buffer
and do not count towards the 39-character limit. If more than 39 characters are entered, or if a syntax error is
encountered in the command sequence, the modem returns an ERROR result code, and the command input
is ignored.
The modem will acknowledge most commands almost immediately. As soon as you type in a command ending
with the carriage return character, your modem will respond with OK.
ATTENTION
+++
This is one of the two commands that do not use the AT prefix. The 3
“plus” signs are used for the Escape
Character Sequence. After you have connected to another modem, you may need to return to command mode
to modify the modem’s configuration or to hang up. To do this, leave your keyboard idle (do not press any
keys) for at leas
t one second, and then press “+”
three times. You do not need to press the Enter key. After a
moment, the modem will respond with OK, indicating that Command mode is now active.
Starting Moxa Terminal Emulator
The following instructions explain how to install the Moxa PComm Lite Package. After installing PComm Lite,
you can use the built-in Moxa Terminal Emulator to handle your modem operations.
ATTENTION
OnCell Terminal Emulator is designed for Windows 2000, XP, 2003, and Vista. If you are running Windows 98,
ME, or NT, use PComm Lite V2.6, which can be downloaded on the Moxa website.
1. Start Terminal Emulator from the Windows Start menu.
2. The PComm Terminal Emulator user interface will appear. Click the Open button, which is the first blue icon
on the tool bar.
