I already tried it with /dev/ttyS0 and /dev/COM1 but doesn't work too. Unfortunately keeping blocking my keyboard. Do you have an example "without block" for serial ? BTW, "COM1" works for me like "/dev/com1" and "/dev/ttyS0" on Cygwin. > Plus, you can probably write setcmc7.c using Cygwin calls as well (instead > of Win32, that is). > Igor Keeping blocking.. :( Could you help me ?
