Chapter 4 - V.22bis Commands
V.22bis DTE/DCE-Modem Interface commands
The parameters defined in this section control the operation of the interface between the DTE/DCE and modem.
E Command Echo
The modem enables or disables the echo of characters to the DTE. The valid parameter value is written to S14 bit 1. Syntax E<value>
Defined Values
<value> Decimal number corresponding to the option.
0Disables command echo.
1Enables command echo. (Default) Result Codes OK <value> = 0 or 1
ERROR Otherwise
Q Quiet Result Codes Control
The command enables or disables the sending of result codes to the DTE. The parameter value, if valid, is written to S14 bit 2.
Syntax Q<value>
Defined Values
<value> Decimal number corresponding to the option.
0Enables result codes to the DTE. (Default)
1Disables result codes to the DTE.
Result Codes OK <value>= 0 or 1
ERROR Otherwise
V Result Code Form
This command selects the sending of
Syntax V<value>
Defined Values
<value> Decimal number corresponding to the selected option.
0Enables
1Enables
Result Codes OK <value>= 0 or 1
ERROR Otherwise
W Connect Message Control
This command, in conjunction with S95 bits 0, 2, and 3, (bits 2 and 3 can be written directly by the host), control the format of CONNECT messages. The actual result code messages reported reflect the W command setting and the S95 bit settings.
The W parameter value, if valid, is written to S31 bits 2 and 3. Syntax W<value>
Defined Values
<value> Decimal number corresponding to the selected option.
0Upon connection, the modem reports only the DTE speed (e.g., CONNECT 19200). Subsequent responses are disabled. (Default)
1Upon connection, the modem reports the modulation, line speed, the error correction protocol, and the DTE speed, respectively. Subsequent responses are disabled.
2Upon connection, the modem reports the DCE speed (e.g., CONNECT 2400). Subsequent responses are
disabled.
