3-6 

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). 

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. 

T - Set Tone Dial Default 

This command forces DTMF dialing until the next P dial modifier or P command is received. The modem will set an S-Register bit to indicate 
that all subsequent dialing should be conducted in tone mode. Note that the DP command will override this command. Clears S14 bit 5. (See 
P.) 

Result Code: 

OK 

Vn - Result Code Form 

This command selects the sending of short-form or long-form result codes to the DTE. The parameter, if valid, is written to S14 bit 3. 

V0 

Enables short-form (terse) result codes. Line feed is not issued before a short-form result code. 

V1 

Enables long-form (verbose) result codes. (Default.) 

Result Codes: 

OK 

n = 0 or 1. 

ERROR 

Otherwise.
