Larry Original Message: ----------------- From: Ton van Overbeek v-overbeek AT cistron DOT nl Date: Wed, 13 Nov 2002 22:20:53 +0100 To: cygwin AT cygwin DOT com Subject: Serial port problems with cygwin1.dll 1.3.15 on Win98SE When using a cross debugger (m68k-palmos-gdb) talking to a Palm device via the serial port on W98SE my system completely hangs. What I have been able to deduce is that it happens as soon as the Palm sends a debug packet to the PC. M68k-palmos-gdb opens the serial port, sets the baudrate to 57600 and puts the port in raw mode. You can still interrupt the program and do other things after this, provided the Palm has not sent any data yet. As soon as it sends data (e.g. when you start the program you want to debug) the whole system hangs. Ctrl-Alt-Delete gives a blue screen etc. I went back to older versions of cygwin1.dll and everything works fine up to version 1.3.14. So something happened between 1.3.14 and 1.3.15. I suspect some of the recent changes to fhandler-serial.cc. Any hints on how to debug this? snapshots to try? Output from cygcheck -s -r -v attached.
