It works fine when using the *real* serial ports, but hangs whenever I attempt to use the virtual ports. The virtual port software works with other win32 applications, and the docs say they drivers do not support DOS apps. Is gdb considered a DOS app? Does it use the win32 API to talk to the serial ports? All I can find in the code is calls to open, read and write, not OpenFile, ReadFile or WriteFile as I would expect for a win32 application.
