Typing Commands
• 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 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 except A/, +++, and A> must begin with the AT prefix and be entered by pressing ENTER.
• The maximum command length is 58 characters. The modem doesn’t count the AT prefix, carriage returns, or spaces.
NOTE: All defaults are based on the &F1Hardware Flow Control template loaded in NVRAM when the
modem is shipped. Defaults are listed in italics.
