Response codes are messages sent from the modem which are
displayed on your PC’s monitor. These messages are the
modem’s response to commands you have sent to the modem.
They can inform you of the status of a call (RING, NO
ANSWER), or whether or not a command is valid (OK, ERROR),
or whether or not the modem has connected using error control
(CONNECT 14400/REL).
Response codes can be displayed as either words or numbers.
The KeepInTouch PCMCIA modem is set up in the factory to
display responses as words. If your computer requires that you
use the numbers format instead, use the V command (see
page 4-5). Other commands that control response codes are Q
and X.
The Q command is used to turn response codes on or off. When
Q0 is set, response codes are turned on (enabled). When Q1 is
set, response codes are turned off (disabled). Refer to page 4-5
for more information on the Q command.
The X command determines which response codes are reported
by the modem. There are two different sets of response codes,
Basic and Extended. Basic response codes report only a
minimal amount of information (OK, CONNECT, RING, NO
CARRIER, and ERROR). Extended response codes provide
more detailed information about connection data rates, flow
control, and data compression protocols. Extended response
codes can also provide you with the reason why a connection
failed (NO ANSWER, BUSY, or NO DIALTONE).
To set the modem to display only Basic response codes, use the
X0 command. For Extended response codes, use one of the
other settings for the X command, X1–X7.
