Sample Result Codes
The following result codes are returned when your computer rate is set to 38,400 bps in your telecommunications software; your modem connects to a 9600 bps modem that supports V.42; and result codes are enabled (ATQØ); set to be returned as words (ATV1); and set to report throughput, error correction, and connection rate (ATW1).
CARRIER 9600
PROTOCOL: LAPM
CONNECT 38400
These results codes indicate a 9600 bps connection rate, LAPM (V.42) error correction, and 38,400 bps maximum throughput.
With the same example, ATWØ would return only CONNECT 38400 (computer rate) and ATW2 would return only CONNECT 9600 (connection rate).
Which Result Codes Should You Use?
The result code commands you need depend on your software. It is nice to have all of the codes turned on, but some software only expects a CONNECT XXXX result code and may get confused with the extra information provided by a command such as W1. The factory default settings ensure compatibility with most software.
