OK, that was a good idea to strip out all of the unused code.
When you do that, you are left with the following function. It still 
does not work but is easier to see what is not working.
fileDescriptor is never -1
Therefore, it never thinks the port is busy even when it is.
This is beyond my skills. Don't know what to try next.

Rich,

perhaps you may check the variable "pathC".

Finally a hint: If you happen to own a full version of BBEdit then 
you can quickly search the FB-Headers folder by "Multi-File Search" 
for variables and FNs. Hence you get a quick impression of items 
involved in a certain FB-Function such as FN TermGetStatus(WhichPort).

Good luck
