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 except A/ and +++ 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.
