DTE-Modem Interface Commands

The parameters defined in this section control the operation of the interface between the DTE and modem.

Command: E	Command Echo
Description:	The modem enables or disables the echo of characters to the DTE. The
	parameter value, if valid, is written to S14 bit 1.
Default:	1
Defined Values:	E0	Disables command echo.
	E1	Enables command echo.
Result Codes:	OK
	Otherwise ERROR

Command: Q	Quiet Result Code Control
Description:	Enables or disables the sending of result codes to the DTE. The parameter
	value, if valid, is written to S14 bit 2.
Default:	0
Defined Values:	Q0	Enables result codes to the DTE.
	Q1	Disables result codes to the DTE.
Result Codes:	OK
	Otherwise ERROR

Command: V	Result Code Form
Description:	Selects the sending of short-form or long-form result codes to the DTE.
	The parameter, if valid, is written to S14 bit 3.
Default:	1
Defined Values:	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.
Result Codes:	OK
	Otherwise ERROR

Command: W	Connect Message Control
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.
Default:	0
Defined Values:	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.
Result Codes:	OK
	Otherwise ERROR
