Specifically, some of my workstations here have /dev/com1 and some don't. What version of the Cygwin DLL is required to get serial port access to work? Also, should /dev/ttyS0 etc work? When I use ls I get strange results... jules:~$ ls -l /dev/com1 crw-rw-rw- 1 Everyone Everyone 7, 1 Jul 20 16:02 /dev/com1 jules:~$ ls -l /dev/ttyS0 crw-rw-rw- 1 Everyone Everyone 7, 0 Jul 20 16:02 /dev/ttyS0 surely these two should refer to the same device, as the 'com1' entry is (presumably) for compatibility with windows conventions and should therefore be a reference to the first serial device, as should ttyS0 for compatibility with unix conventions...? Also, is there any chance of having a virtual /dev directory that lists available devices? Or do I have to 'mknod' them all by hand?
