PROBLEM
Errors are constantly occurring in your V.17 fax transmissions.
POSSIBLE SOLUTION
Your modem initialization string may be insufficient for fax transmissions. In terminal mode,
type the following initialization string: AT&H3&I2&R2S7=90S36=0 then press ENTER. The
standard string for faxing is AT&F1S36=0.
POSSIBLE SOLUTION
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. 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.
POSSIBLE SOLUTION
Your baud rate may be set too high. In your communications software, lower the baud rate to
9600, 7200, or 4800.
