AT Commands
The OMEGA CDMA Modem stores the last-executed command line in memory until it
executes a new one. To re-execute the last command line you sent, type
A/
without typing
AT
or
at
in front of it or pressing <cr> after typing it. If the modem is reset or loses power,
the last-executed command is lost from memory. This renders the
A/
command useless until
the modem executes a command line.
Result Codes
By default, when you send a command line to the OMEGA CDMA Modem, the OMEGA
CDMA Modem sends a result code such as
OK
. This is because the default
Q0
command is in
effect. To disable result codes, issue the
Q1
command. To reactivate result codes, issue the
Q0
command.
When result codes are enabled (Q0 is in effect), you can select the result code sets from which
the result codes are fetched. The OMEGA CDMA Modem provides six result code sets,
designated
X1
through
X4
. Table A-7 on page 27 lists the result codes contained in each result
code set.
Result codes can appear as English words or numbers, depending on the Vn command in effect.
The
V1
command enables word result codes. Word result codes are followed by a carriage return
and line feed. The
V0
command enables numeric responses. Numeric result codes are followed
by a carriage return only. Numeric result codes are useful if the OMEGA CDMA Modem is
operating under an application that either cannot handle character strings or handles them
inefficiently.
