Hi stickybeak, welcome to our forum.
This message,
"Cannot access comm port. The port may not be present or another app may be using it" means exactly what it says; something else is using the PC's COM port you have selected. You must either select a different COM port or check to see if anything else is using it and stop that software.
Common things that utilize COM ports:
- RSLogix
- PDA Software (Palm Pilot, Pocket PC, etc.)
- GPS Software
- Digital Camera Software
- IR (infrared) Drivers
- Microsoft ActiveSync
- Palm OS HotSync
