OK, that's kernel version 2.4.

I just tried "rk" on my machine running 2.4.19 and it worked fine.  But,
I'm not running RedHat (I run Debian).

That means it's not showing predictions.

OK, then the pseudo-ttys are probably working.  "rk" doesn't issue a
warning before it starts up, right?  Something like

Unable to open a pty

?

Excellent.

In system.h, you'll see:

#if defined(FLG_HPUX_UNIX) || defined(FLG_SOLARIS_UNIX) || defined(FLG_LINUX_UNIX)

Try getting rid of the "|| defined(FLG_LINUX_UNIX)" part and recompile.
This will (presumably) try using the BSD tty interface.  If you get
compilation errors, then it's probably not right.

You might add "|| defined(FLG_LINUX_UNIX)" to the end of this line

#if defined(FLG_AIX_UNIX) || defined(FLG_SGI_UNIX)

in system.h and try compiling.  Again, compilation errors will probably
indicate that this change won't work.

I'll send you another e-mail after this one with my "rk" binary.  Try that
out.
