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. This
does not include the AT prefix, carriage returns, or spaces.
Note: All defaults are based on the &F1, the
Hardware Flow Control template loaded in NVRAM when
the modem is shipped. Defaults are listed in italics.
