beginning of this chapter showing result codes in both long and short
formats..
Type the command ATV or ATV0 to select numeric result codes. The
factory default is to display the result codes as words (ATV1). You should
issue an ATV1 command either to reset the factory default after a change
has been made or to select the long-form (word) result codes. Negotiation
progress messages (extended result codes) are those with a numerical value
of 40 or more.
Four other AT commands, two dial modifiers, and an S-Register are also
directly involved in the generation and display of result codes. These are
the ATQn, ATVn, ATWn, and ATXn commands, the ATDW and
ATD@ dial modifiers, and S-Register S95.
Wn Negotiation Progress Message Selection
The ATWn command, where n represents 0, 1, or 2, works in conjunction
with S-Register S95 to determine how that subset of the result codes
called negotiation progress messages or extended result codes will be
used to report the type of connection, protocol, and other communication
techniques that resulted from handshaking and subsequent negotiation.
The options available to represent n in the ATWn command are:
W0 CONNECT result code reports DTE speed. If S-
Register S95=0, disable the display of all extended
result codes.
W1 CONNECT result code reports DTE speed. If S-
Register S95=0, enable the display of CARRIER and
PROTOCOL extended result codes only.
W2 CONNECT result code reports DCE (modem-to-
modem) speed. If S-Register S95=0, disable the display
of all extended result codes.
Xn Result Code Set/Call Progress Option
The ATXn command, where n represents 0-4, controls how the modem
responds to dial tone and busy signals and how it displays CONNECT
result codes. The options available to specify with the ATXn command
