Hi, I have a PC with multiple serial ports. One of the COM port is the regular COM1 that comes with most PCs. The other ports are all located on a PCI card. Under windows, those ports are mapped to COM3, 4, 5, and 6. Under Linux, they are mapped to /dev/ttyS2, /dev/ttyS3, /dev/ttyS4, and /dev/ttyS5 as one would expect. I wrote a program to read all those ports one at a time. The program works without any problem under Linux.
However, when I tried to run the same program under cygwin, I could only read /dev/ttyS0. The program is unable to read any data from the serial ports on the PCI card. I ran "stty -a" to determine what serial ports cygwin is seeing on the machine, and I noticed that only "line 0" settings were reported. So, either cygwin does not support serial ports on PCI cards or I need to configure it properly to handle those cards. I've been googling around to find some information about this, but I haven't found anything so far. Any help would be really appreciated.
