VNC slow with DOS based apps

Hi all,

I am running RealVNC to access a Windows 98 SE machine.
While VNC works fine with Windows based applications when it comes to DOS based software it is incredibly slow. I can hit a key and have to wait for a couple of seconds before the system reacts.

I have also tried using ultraVNC and set the options to the lowest possible and the lag still remains.

Any suggestions appreciated??

    DOS is tough on VNC apparently.

    Did you check the VNC documentation.

    There may be settings on the DOS box properties that will make it easier, but I am not sure.

    I would do some testing.

    I hope this helps !

    yep i have checked the VNC documentation for realVNC with no luck.

    I had a look through the settings but again nothing seemed to make a difference.

    Does anyone know of any VNC software that works with DOS based progs running in Windows 98?
