	No-no. The problem is somewhere in OpenDOS or in DJGPP run-time
libraries, "rawkeyboard" can not help. For example, here is the small 
example (and even classic) program:

#include <stdio.h>

int
main (void)
{
	char ch;

	while ((ch = getchar ()) != EOF)
		putchar (ch);
}

Compile it and run under dosemu. If your host DOS is Caldera OpenDOS,
dosemu will hang (only ctrl-alt-pgdn works) when you start this program.
If you use stdin redirection, everything is fine. *Very* seldom it is
possible to type anything on the standard input but in next run dosemu
will hang again.

Nate> Btw: Is dosemu 0.99.x out? Last I checked, they were still at
Nate> 0.66. Where did you get it?

	It is available from ftp://ftp.suse.com, but do not forget to
set "threshold" parameter in /etc/dosemu.conf to zero or Emacs will 
draw on screen with incredible low speed.
