BOCA PRO16 Reference Guide
FIf your modem receives a character from your computer while dialing
is being performed, it will immediately hang up, send a NO CARRIER
response message to the computer and return to local command state.
After a few seconds the message CONNECT will appear on the screen.
If a NO CARRIER message appears, then your modem has not been able
to make a connection. Check your communications software is set for
2400 bps operation and your modem is correctly connected to your
computer and the telephone line. You may use the A/ command to
redial.
To hang up the modem, enter an escape sequence (+++). The modem
will respond with an OK message.
• Type:
ATH <E>
The modem will hang up.
FYour computer must assert the DTR signal before dialing can start.
Usually, this is done by your communications software. If the DTR
signal is lowered at any stage of communications, after the &D2
command has been issued, the modem will hang up and return to local
command state. Interpretation of the DTR signal may be changed with
the &D command.
Dial Modifiers
Dial modifiers are characters than can be included in a phone number to
make the modem perform special tasks while dialing.
For example, not all modem users will be using a dedicated telephone
line. Some users will have their modems connected to PBXs. To allow
users of PBXs to operate their modems successfully, dial modifiers are
supported on the modem.
Most PBXs require you to dial 0 or 9 (in order to obtain an outside line)
and wait for a dial tone before dialing the actual phone number.
Using dial modifiers, you can successfully dial the phone number 12345
through a PBX using the command:
ATD0,12345
