Cannot upload to Prop - Com port problems
I have a Propeller Project board. When in the Prop Tool (2.7.0 Beta) I 'Identify Hardware', it finds the prop on COM2. However, if I try to compile and upload to the prop, the Prop Tool complains that "no propeller was found on any serial port. Scanned COM 2. One serial port was excluded from the search". If I go to 'Edit ports' via Edit -> Preferences, the only port showing active (i.e., bold) is COM 2. Setting the search to 'AUTO' or specifying COM 2 makes no difference. A different PC makes no difference. A different prop board makes no difference. v2.9.3 of the Prop Tool makes no difference. The drivers are up to date. Obsessionally, the message is "More than ten serial ports were excluded from the search. Click Edit Ports for more information". The Edit ports dialogue shows only COM 1 and COM 2, as does Windows Device Manager.
Flexprop works perfectly.
Any suggestions gratefully received.
