Command Summary

· 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 since it is not stored in the modem

buffer.)

· If a command has numeric options and you don’t include a number, zero is assumed. For example, if

you type ATB, the command ATB0 is assumed.

· Every command but A/, +++ and A> must begin with the AT prefix and be entered by pressing a

carriage return (Enter key).

· The maximum command length is 60 characters. The modem doesn’t count the AT prefix, carriage

returns, or spaces.

Note:

Defaults are marked with an asterisk (*).

AT prefix or carriage return.
