Modem problems
This section lists common modem problems.
The modem will not receive or transmit properly.
Make sure the RJ11 cable (the one on the right side of the
computer that goes from the modem to the telephone line) is
firmly connected to the computer’s modem port and the telephone
line socket.
Check the serial port settings to make sure the hardware and
software are referring to the same COM port (look in Device
Manager under Modems for the built-in modem).
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. Refer to the
program’s documentation and the modem manual for information
on how to change these settings.
The modem is on, set up properly and still will 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.

programs build in an automatic backup, but you should not rely
