AT Command Reference Manual
3-8 1048
P - Set Pulse Dial Default
This command forces pulse dialing until the next T dial modifier or T command is received. Sets S14 bit 5.
As soon as a dial command is executed which explicitly specifies the dialing mode for that particular call (e.g., ATDT...), this
command is overridden so that all future dialing will be tone dialed. (See T command.)
This command may not be permitted in some countries.
Result Code:
OK
Qn - Quiet Results Codes Control
The command enables or disables the sending of result codes to the DTE according to the parameter supplied. The
parameter value, if valid, is written to S14 bit 2.
Q0 Enables result codes to the DTE. (Default.)
Q1 Disables result codes to the DTE.
Result Codes:
OK n = 0 or 1.
ERROR Otherwise.
Sn - Read/Write S-Register
The modem selects an S-Register, performs an S-Register read or write function, or reports the value of an S-Register.
n Establishes S-Register n as the last register accessed.
n=v Sets S-Register n to the value v.
n? Reports the value of S-Register n.
The parameter n can be omitted, in which case the last S-Register accessed will be assumed. The S can be omitted for AT=
and AT?, in which case the last S-Register accessed will be assumed.
For example:
ATS7 establishes S7 as the last accessed register.
AT=40 sets the contents of the last register accessed to 40.
ATS=20 sets the contents of the last register accessed to 20.
If the number "n" is beyond the range of the S-Registers available, the modem will return the ERROR message. The value
"v" is "MOD"ed with 256. If the result is outside the range permitted for a given S-Register the values will still be stored, but
functionally the lower and higher limits will be observed. Input and output are always in decimal format. Note that some S-
Registers are read-only.
In some cases, writing to the S-Register will appear to be accepted but the value will not actually be written.
Due to country restrictions, some commands will be accepted, but the value may be limited and replaced by a maximum or
minimum value.
Minimum, maximum, and default values for S-Registers may be altered with ConfigurACE.
