Hi Douglas

There are two different things to check

1) If the control (OCX) is properly installed on the machine
2) If the COM ports are properly configured and accessed by the OS

Regarding the first point, if you have setup VFP 5.0 on the machine, the control is installed. You can verify it looking at the list in Options / Controls / ActiveX Controls, it should appear as Microsoft Communication Control (you don't need to check the option, that only means adding it or not to the form designer toolbox).

I guess this is not the problem because if it was not installed, it should fail when you try to instanciate the control, not in the Open command

The second point is probably failing.
First of all, look for the port at My PC -> Properties -> Hardware -> Device Manager -> Ports; the corresponding port should be listed there and its properties (General tab) should show that the device is enabled and working properly.
If it is not, try to install it / fix it with the Hardware Wizard.
(It may even be disabled by the BIOS setup, you may need to check there if the Hardware Wizard cannot find it)

Hope this helps,
Jose
