Command:
P Set Pulse Dial Default
Values: P, T
Default: T
Description:
This command forces pulse dialing until the next T dial modifier of T command is received. As
soon as a dial command is executed which 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.
Command:
Qn Quiet Result Codes Enable/Disable
Values: n = 0 or 1
Default: 0
Description: The command enables or disables the sending of result codes to the DTE. The
parameter value, if valid, is written to S14 bit 2.
Q0 Enables result codes to the DTE.
Q1 Disables result codes to the DTE.
Command: T Set Tone Dial Default
Values: P, T
Default: T
Description:
This command forces DTMF dialing until the next P dial modifier or P command is received.
The modem will set an S-Parameter bit to indicate that all subsequent dialing should be
conducted in tone mode. The DP command will override this command. This command may
not be permitted in some countries.
Command:
Vn Result Code Form (Not available in V.22bis)
Values: n = 0 or 1
Default: 1
Description:
This command selects the sending of short-form or long-form result codes to the DTE.
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.
Command:
Wn Connect Message Control
Values: n = 0, 1, or 2
Default: 0
Description:
This command, in conjunction with S95 bits 0, 2, 3, and 5 (bits 2, 3, and 5 can be written
directly by the host or by the +MR, +ER, and +DR commands, respectively), control the
format of CONNECT messages. The actual result code messages reported reflect the W
command setting and the S95 bit settings. (Also see +MR, +ER, and +DR commands.)
The W parameter value, if valid, is written to S31 bits 2 and 3.
W0 Upon connection, the modem reports only the DTE speed (e.g., CONNECT 19200).
Subsequent responses are disabled.
W1 Upon connection, the modem reports the modulation, line speed, the error correction
protocol, and the DTE speed, respectively. Subsequent responses are disabled.
W2 Upon connection, the modem reports the DCE speed (e.g., CONNECT 14400).
Subsequent responses are disabled.
