If a connection can be made to a remote modem a CNX indicator will be
sent by the modem. If a CFI AB indicator appears, your modem has not
been able to make a connection.
To hang up the modem, your computer or communications software
must make DTR low.
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 by your 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:
• Type: CRN 0<12345
