The DCE can be configures to use different response codes depending on the V.250 command that is enabled (AT+MR, AT+ER, AT+DR, and AT+ILRR). Alternatively, the ATWn command can be used to set these V.250 commands. The mapping for the ATWn command to V.250 commands is shown in Table 14. The setting for the ATXn command (page 43) can affect which ATWn response codes are reported to the DCE. The ATXn command configures the modem call progress detection and reporting requirements during dialing (for example, dial tone and busy tone detection). The ATQn command selects whether the modem sends result codes to the DTE.

For example, a connection is established with the remote modem as shown below (with LAPM error correction and V.42 bis data compression). The telephone line (or modem-to-modem connection) data rate is 33,600 bps and the local UART (DTE-to-modem) connection rate is 115,200 bps.

The modem then sends the ‘CONNECT’ messages for the following four Wn commands:

•ATW0

ILRR: 115200

CONNECT 50666

•ATW2

+MCR: V90

+MRR: 28800 CONNECT 50666
