5. Command Summary
·Type commands in either upper or lower case. Do not use a
combination of upper and lower case characters.
·Use the Backspace key to delete errors. Note that the original AT
command is stored in the modem buffer, and cannot be deleted.
·Some commands have numeric options. If these commands are
invoked without a numeric option, the modem will assume option
0 (zero). For example, when the command ATB is invoked, the
modem will assume command ATB0 was intended.
·All commands begin with the AT prefix, and are invoked by
pressing [Enter] (Carriage Return). The only exceptions are the
A/ command (Repeat previous command) and +++ (Exit to on-
line command mode).
·The maximum command length is 40 characters. This does not
include the AT prefix, Carriage Returns, or spaces.
Note:
•All defaults are based on the &F1-Hardware Flow
Control template loaded in NVRAM.
•Defaults are marked with an asterisk (*).
