Well, Frank seems to be right. I have 0.39.2extended-test4.exe on XP; I have changed the actual com number by doing

control panel->system->device manager->bluetooth devices and changing the com number for my device to com 2.

That seems to work fine.

I have always wondered why these limitations are put in place? Why limit things like that? Surely the memory usage difference is minimal in comparison with the hassle that arises from hitting the limitations? Or am I missing something?

Thanks for the help. I don't think I would have been close to a solution without it.

I think you have an older version of comport.

The sys_com_port array is not there. There is just this in the latest version of comport.c in cvs:

#define COMPORT_MAX 99
so you should be able to open COM1 through COM98.
