I am using Modbus Test kit is an implementation of the Modbus protocol in python (http://code.google.com/p/modbus-tk/)
This uses pySerial
When using a Virtual COM Port ( Windows XP PC) I get the following error ...
"Error while handling request, Exception occurred: WriteFile failed ([Error 995]
The I/O operation has been aborted because of either a thread exit or an application request.)"
Opening and reading the serial port is ok but when try to write you get this error
What does this mean?
