[Wine] RS232 connection

[Giorgio]

I installed Board Master a software that control a CNC machine to produce PCB (Printed Circuit Board).
The software install flawlessly but to check if it works I need RS232 working to control CNC machine.
I tried to set connection parameters in Board Master choosing COM1 (the only available) but CNC machine don't move and software keep asking for switching machine on.
Of course software and CNC works in Windows XP.

1) is RS232 working on Wine ?

2) if yes how can I check it ?
