I have a DJGPP program executing a fairly long loop containing kbhit() to 
check for keyboard input. When executing normally, it works fine, but as 
soon as the program is invoked using GDB (version 6.1.1), the kbhit() never 
returns anything but 0 when using CWSDPMI under ROM-DOS. This is the 
case even if just running the program without setting any breakpoints or 
watchpoints.

GDB works fine in a DOS-BOX in WinXP.

I have tried both DJGPP 2.03 and 2.04 with the same result.

Any help will be appreciated.
