Error: COM ERROR 8

Solution or Workaround

This error occurs while digitizing coordinates:

COM ERROR 8  

Cause

This is a framing error, most likely due to differences between the configuration of the digitizer's serial port and settings in the difgorm file.

Answer

Check the digitizer settings and the CON-DIG settings to make sure they are the same as per configuration notes for your digitizer.

Note:
This error is common with the Calcomp DrawingBoard III as it alters the default configuration settings.
