TECHNICAL REFERENCE

Typing Commands

• In terminal mode, type commands in either upper or lower case, not a combination. Use the Backspace

key to delete errors. (You cannot delete the original AT command because it is stored in the modem

buffer.)

• If a command has numeric options and you do not include a number, zero is assumed. For example, if

you type ATB, the command ATB0 is assumed.

• Every command except A/, +++, and A> must begin with the AT prefix and be entered by pressing

ENTER.

• The maximum command length is 58 characters. This does not include the AT prefix, carriage returns, or

spaces.

All defaults are based on the &F1Hardware Flow Control template when the modem

is shipped. Defaults are listed in italics.
