B
Set Transmission Method
The B command can be used to operate your modem in Bell and/or CCITT mode
depending on the DTE baud rate and on whether your modem is generating or
answering a call. Table 6-1 on page 6-28 shows how this command works.
D
Dialing
The D command instructs your modem to dial a number. Enter the number that wish
to dial after the D command. You can modify the D command with the following
additional commands:
P
Pulse Dialing
The P modifier generates the call using pulse dialing (German standard).
Enter the modifier after the command, followed by the desired telephone
number.
T
Tone Dialing
The T modifier instructs the modem to use tone dialing. Enter the modifier
after the command, followed by the desired telephone number.
W
Wait for a Dial Tone
The W modified instructs the modem to wait for a second dial tone. Use
this command in private branch exchanges to wait for a dial tone after
calling an outside line.
Example: ATDP0W555-1111
This command dials 0 for an outside line, waits for a second dial tone and
then dials the number 555-1111.
,
Pause
This modifier inserts a 2-second pause before dialing. If, for example, your
modem is located in a private branch exchange (e.g., in offices), where a
number (usually 0) must be dialed for an outside line, insert a comma
between the 0 and the actual telephone number you wish to dial. Your
modem dials 0, waits for two seconds and then dials the telephone
number. If a longer pause is required, you can either insert another comma
in the command line or change the value of the S8 register (see
page 6-23).
@
Wait for Five Seconds of Silence
This modifier instructs the modem to wait until no tone has been detected
on the line for five seconds before dialing the specified number.
