Could you compile cygwin1.dll with the following patch:
diff -u -p -r1.35 fhandler_serial.cc
--- fhandler_serial.cc 7 Nov 2002 18:47:21 -0000 1.35

Some more input.
Attached strace output from a successfull run with the cygwin-1.3.14
dll. What I can spot in the log is that when com4 is read it now has a
read timeout of 1000 (vtime=1000), while in the unsuccessfull runs vmin
was 0. Does that ring any bells ?
