TROUBLESHOOTING AND ONLINE HELP RESOURCES

Diagnosis:

The serial port rate in your communications

software may be set too high for your

modem’s UART or your area’s phone lines.

Possible Solution:

Lower the serial port rate in your

communications software to 57,600 bps,

38,400 bps, or 19,200 bps.

Diagnosis:

The remote site you are dialing into may have

trouble with the file transfer protocol.

Possible Solution:

Try using a different file transfer protocol. Do

not use Xmodem if other protocols are

available. Zmodem is the preferred protocol.

Diagnosis:

There may be a Terminate and Stay Resident

(TSR) program (such as a screen saver or

virus scanner) running in the background,

disrupting data communications.

Possible Solution:

Disable any Terminate and Stay Resident

(TSR) programs running in the background.

If you have software running as a TSR, check

the software’s manual for information about

disabling its ability to operate as a TSR.

Diagnosis:

You may be trying to download a file to a

compressed area of your hard disk.

Possible Solution:

Download to an uncompressed area on your

hard drive.
