#490 keyboard controls don't work when using gopherus

[Mateusz Viste]

I'd like to report a bug I noticed when using dosemu-1.4.0.8-120-ga2fe2a2 (pulled out from git and compiled on my system):

when I run the 'gopherus' gopher client, keyboard controls do not work (or maybe DOSemu freezes, it's hard to tell). The main screen of gopherus appears correctly, but pressing UP/DOWN arrows nor ESC doesn't trigger any reaction.

This problem doesn't happen with DOSemu v1.4.0.1 (installed as a package from opensuse repositories).

gopherus is a DJGPP-compiled Gopher client for DOS using Watt32: http://www.viste-family.net/mateusz/software/gopherus/

For me it only says

Configuring through BOOTP..

and nothing more.

Could you please provide a "demo" version
of that prog, so that I can reproduce the
problem without dealing with the networking stuff?

[Mateusz Viste]

Sure! I looked into gopherus code to find out what is the problem, and I prepared a small program that allows to easily reproduce the problem. I am attaching the binary file (compiled with DJGPP). It is supposed to wait for a keypress, and print the key's code. Works fine with DOSemu 1.4.1, but do not catch anything on DOSemu 1.4.8.

The program is as simple as this:

/*
 * Test program using getkey() for DOSemu bug #490
 * Author: Mateusz Viste
 */

#include <stdio.h>

int main() {
  int keypress;

  keypress = getkey();
  if (keypress == 0x00) { /* handle extended keys */
    keypress = getkey();
    keypress |= 0x100;
  }
  printf("You pressed: 0x%02X\n", keypress);
  return(0);
}

Now fixed in git, thank you for test-case.
