/dev is internal to cygwin only.  There is no /dev directory, like on
linux.

However, certain /dev devices are recognized by cygwin.

The com ports are referenced via '/dev/com0', '/dev/com1', etc.
You should also be able to use '/dev/ttyS0'.  It should be an alias
for '/dev/com0'.

Be advised that the tcset* settings for com ports is not fully
implemented.  This probably won't affect you unless you're trying to
attach an interactive shell to a com port.
