Owner’s Manual

Data is being lost

•If you are using data compression, be sure the serial port baud rate is set to a minimum of four times the data rate.

•Make sure the flow control method you selected in software matches the method selected in the modem. If you are using CompuServe’s WinCIM software, you must set the modem for XON/OFF flow control (see Chapter 2 for the CompuServe initialization string).

•Try entering the &V (View Parameters) command, making a screen print of the diagnostics listing, and checking for parameters that may be unacceptable.

There are garbage characters on the monitor

•Your computer and the remote computer may be set to different word lengths, stop bits, or parities. If you have connected at 8-N-1, try changing to 7-E-1, or vice-versa, using your communications software.

•You may be experiencing line noise. Enable error correction if it is disabled. Or, hang up and call again; you may get a better connection.

•At speeds above 2400 bps, the remote modem may not use the same transmission or error correction standards as your modem. Try connecting at a slower speed or disabling error correction. (With no error correction, however, line noise can cause garbage characters.)

•Try entering the &V (View Parameters) command, making a screen print of the diagnostics listing, and checking for parameters that may be unacceptable.

Fax and data software won’t run at the same time

•You can have Windows 95 compliant data and fax communication applications open at the same time, but they cannot use the same modem at the same time. Make sure no other application is online when you try to dial out. If you are using legacy communications software with Windows 95, you may get a message that another application is occupying the device even when no call is in progress. Close any open legacy communications programs and try again.
