Hello, thank you Corinna, your message removed some of my headache.
May I ask to confirm and eventually add to documentation? 1. cygwin does support 16 serial deviecs with 'dev/com1' to '/dev/com16' 2. By using Windows names like '//./com1' cygwin does not recognize the interfaces as interfaces but as ordinary files. 3. If you want to use serial interfaces in a 'hardware' oriented approach (i.e. read out the modem lines DCD, DSR, change the interface settings baudrate, parity, etc. etc.) you should only use Win32-API functions. May I additionally ask? - is there a reason on limiting to 16 supported serial interfaces in Cygwin? - if no, is it an idead to increase this number? - I used the POSIX functions read() write() and select() to communicate with my serial interfaces and the Win32-API functions to set baudrate and to get modem line status. It worked until now. Are there hidden pitfalls ? Are there POSIX/Cygwin functions to do the same job ? Again, thank you very much for your Help.
