[Elecraft] KPA500 Port problem

[Tim C]

I live in a nursing home and am mobility impaired and must control my KPA500 with my computer.  I saved for over a year for the amp.  My KPA500 will stay connect to my computer for <2 min and the Utility locks up and the only way to get it to load again is to re-boot the computer.  The error messages I receive all say the port is in use which it is not.  I have uninstalled and re-install the FTID comport driver many times.  The baud rate of 38400 for both computer and amp.  I have downgraded and up graded the firmware.
