Modem problems
(Available on certain models.)
This section lists common modem problems.
The modem will not receive or transmit properly.
Make sure the cable from the modem to the telephone line is firmly
connected to the computer’s modem port and the telephone line
jack.
Check the communications parameters (baud rate, parity, data
length and stop bits) specified in the communications program. It
should be set up to transmit at 300, 1200, 2400, 4800, 9600, 14400,
28800, 33600 bps (bits per second) or higher.
The modem is on, set up properly but still does not transmit
or receive data.
Make sure the line has a dial tone. Connect a telephone handset to
the line to check this.
The other system may be busy or off line. Try making a test
transmission to someone else.
