I need to manage several serial port in several process in 4D V19 on windows
Someone know ho i can do?
Is possible this sequence on several process?
1 - if semaphore of com1 is unused, open com1
2 - Use com1
3 - Close com1 with command SET CHANNEL(11)
During this steps if another process want to use COM1 and sempahore is
locked, the process wait
Thanks
Ferdinando
