Any known limitations in SPORT on the number of COM ports?

Hi All,

I have some routines that use the SPORT routines in the IFPORT library to access RS232 ports. Until now, I have had no problem using the SPORT routines; however, when I attempt to access COM port 10, I an unable to get any communication across port 10. All other ports (1-9) work fine, and other window's-based programs are able to communicate over COM10, so it is not a hardware issue. Only when I try to write/read/open/acess COM10 via SPORT routines does the problem arrise.

The communication is very simple, so I don't see any problems in the fortran code. Has anyone else had a problem accessing COM ports greater than 9?

Thanks!
