The ATV command determines whether the modem re- turns result codes as words (default), such as OK and ERROR, or as numbers. Generally, persons writing programs use numeric result codes. ATV0 returns codes as numbers; ATV1 returns result codes as words. * The ATXn command enables certain sets of result codes. Result codes 0 to 4 are the basic, default result code set; result codes 5 to 7 and 10 to 12 are the extended result code set. * In error-control mode, the modem's DTE (modem-to-computer) speed result codes (CONNECT) can be higher than the DCE (modem-to-modem) speed (indi- cated by CARRIER) due to the modem's ability to compress data and accept data at a higher rate.
