Crashes if running WordPerfect 5.1

Hello.

You can set

$_mapping = "mapfile"

in your dosemu.conf.

Hi,

The patch below also does the job. As far as I could see DPMI no longer calls this function so I guess I could remove the comment whilst I was at it.

I find that since upgrading to dosemu-1.2.1 I can not access F11 and F12 in MegaDots, a program for braille translation and formatting. When I try F11 or F12 in this program, it complains about that macro not existing. Is this a known program and is there something I can do about it? Thanks.

depends where you use it. Terminal? Console? X?
On the console $_rawkeyboard may help (dosemu -k). Otherwise try shift-f1, many terminals don't distinguish between shift-f1 and f11. If all else fails ctrl-6 - (that is ctrl+six then minus) and ctrl-6 = should work.

Bart

It is the console I am using, and the ctrl-6 combinations worked. Thanks.

Are there a complete list of the function keys (with combinations) you can use if you run dosemu for instance through SSH?
Lars

Yes, it worked! What happens when you spesify that?
