send the BUSY response.
2.9.5 X4 response set
The X4 response set is the factory-default response set. It consists of the all responses in
Table 2-1(see page 19). This response set allows the modem to detect a dial tone and
also a busy signal.
2.10 Correction & compression responses
If your modem supports the MNP and V.42/V.42bis error-correction and data-compression
protocols, you can use the Wn command to enable the extended responses shown in
Table 2-1(see page 19).
l The W command that enables negotiation progress responses is not the same
command as the W dialing modifier used in dial command lines.
The default setting, W0, disables extended responses. With W0, all CONNECT responses
report the DTE speed.
To receive the CARRIER and PROTOCOL responses in Table 2-1, send the W1
command. When this command is in effect, the CONNECT response will show the DTE
speed.
If you want the CONNECT response to show the DCE speed rather than the DTE speed,
send W2 command. With this command, extended responses will be disabled.
Modems that support the MNP and V.42/V.42bis error-correction and data-compression
protocol can also use the \V1 command to append /ARQ to the end of all CONNECT
responses when your modem makes an error-correction data connection with a remote
modem.
If you do not want /ARQ appended to the end of CONNECT responses when an error-
correction data connection is made, send the \V0 command.
