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 (*).
