Anyway, a couple days ago this appeared in my mailbox. I immediately tried it, and found that it worked. I wanted to find out HOW it worked, so I fired up PFIXPLUS (symbolic debugger), and traced the code through. But, not knowing a thing about 8086 ASM, I was unable to extract the relavent part of MODE.COM to do the switch. Can anyone do this? Unfortunately I cannot post ASM to MODE, as (I assume) it is copyrighted by Compaq. Well, here is the msg, and THANKS to Fred McClimans (?) for this bit of undocumented info. --Erik ----------------------------Fold, staple, mutilate-------------------------- Received: from ddn2 (ddn2.arpa) by GODOT.THINK.COM; Thu, 7 Nov 85 11:08:55 est Date: 7 Nov 85 10:52 EST From: McClimans@DDN2.ARPA Subject: Compaq MODE command To: ejb@think.com Cc: McClimans@DDN2.ARPA After putting in some time last night on the Compaq dilemma, I came up with this: MODE SPEED=I don't know if you already hit on this (it isn't in the Compaq doc's), but it is interesting none the less.
