Section Four
Result Codes
CONNECT XXXX If a connection is established
NO CARRIER If retrain is not successful in the time specified by S7
P — Set Pulse Dial as Default
Parameters none
Default none
Causes the modem to assume that all subsequent dial commands are
pulse dialled. The user may omit the "P" from the dial strings.
Qn — Result Code Display
Parameter 0 or 1
Default 0
Determines whether or not the modem returns the result codes (see Xn
command).
Examples
ATQ0 Allows the modem to return result codes
ATQ1 Prohibits the modem from returning result codes
Sn — Read/Write S Registers
Parameters n = 0-95 x = 0-255
Default none
Selects a S register, reads or writes the contents of a S register, or reports
the value of a S register. All the S registers may be read. If no parameter is
entered, S0 is assumed. The “S” can be omitted to assume the last S-
register accessed.
All the registers will return the OK response if x is a legal value; however,
some registers will not actually write the value anywhere.
If the parameter number is beyond the range of the S-registers available,
the modem will return the ERROR message. The value x is “MOD”ed with
256, and 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 is 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.
