define certain dialing characteristics and how the modem handles dial tones and busy
signals, as described in the following sections.
2.9 Word or numeric responses
Modem responses can appear as words or numbers. Your modem is set up to return word
responses. Word responses are followed by a carriage return and line feed.
If your modem is operating under an application that handles character strings inefficiently
or cannot handle them at all, you can use the V0 command to switch to numeric modem
responses. Numeric responses are followed by a carriage return only.
If you do not want to receive modem responses at all, you can use Q1 command to
disable them. You may want to disable responses entirely if your modem is connected to a
printer and you do not want the modem responses printed.
2.9.1 X0 response set
The X0 response set consists of the first five responses in Table 2-1(see page 19). with
this response set, you receive the CONNECT response for all connections, regardless of
the speed at which they're made.
When you send a Dial command line with this response set in effect, the modem will wait
two seconds after receiving your Dial command, then automatically dial the telephone
number whether or not a dial tone is present This is known as "blind dialing." You may
want to use blind dialing if you will be using the modem in an area that has an irregular or
weak dial tone that your modem cannot always detect.
2.9.2 X1 response set
The X1 response set consists of the all responses in Table 2-1 (see page 19), except NO
DIALTONE, BUSY and NO ANSWER. When you send a Dial command with this
response set in effect, your modem will blind dial call.
2.9.3 X2 response set
The X2 response set consists of all responses in Table 2-1(see page 19), except BUSY
and NO ANSWER.
When you send a Dial command with this response set in effect, your modem will listen
for a dial tone before dialing. If it does not detect a dial tone within five seconds, it hangs
up and returns the NO DIALTONE response.
2.9.4 X3 response set
The X3 response set consists of all responses in Table 2-1 (see page 19), except NO
DIALTONE.
When this response set is in effect and you send a Dial command to your modem, your
modem will blind dial the call. If the telephone number dialed is busy, your modem will
