Late to the party regarding this, but there is a lot of misinformation being stated. USB and PS2 protocols are COMPLETELY different from each other -- barely even in the same universe. You can't "convert" from one to the other. You can talk to the mouse hardware with one protocol and then

Re: [Freedos-user] ot: run time issues?

The Runtime Error 200 issue has been around a long time, and is fairly well-known among DOS enthusiasts. It is actually an interesting "feature" of programs that were compiled with Turbo Pascal (TP). Supposedly, the problem occurs in the startup/initialization code of programs, before the

Re: [Freedos-user] Not sure is it possible - but maybe I'm missing som ething?

t, I don't convert an existing program from A86 to NASM until and unless I have to. All of my new programs I do in NASM. Also FWIW, I still prefer the D86/D386 Debugger (though even it has its quirks). The Debugger is at least as, if not more, important as the Assembler itself. Bret -

Re: [Freedos-user] FreeDOS Internet Security Protocols and Graphical I nterface

Thanks for the comments, Karen. I'll check out Lynx once again based on your recommendation and see what I think now. I do see that Lynx recommends my MOUSKEYS program to enable mouse support, so it can't be all bad ;-). It has been a long time since I've tried Lynx, and I don't remember

Re: [Freedos-user] FreeDOS Internet Security Protocols and Graphical I nterface

Hi Karen: I've tried various DOS browsers in the past, and they've all been less than stellar. Arachne, Lynx, Dillo, Links -- all have problems that make them unsuitable for me. Arachne in particular was very unstable for me and seemed to crash constantly. I do like Michael Brutman's MTCP

Re: [Freedos-user] FreeDOS Internet Security Protocols and Graphical I nterface

For the wireless connection, Michael Brutman (maker of MTCP) has this page that discusses another option: http://www.brutman.com/Wireless_for_Classics/Wireless_for_Classics.html I haven't used on of these for DOS, but did use one (the one that Michael recommends) in another application where

Re: [Freedos-user] Using a timer with an ISR in watcom

Just as an FYI, other people have tried to do the same kinds of things (particularly with fast polling of a parallel port) with mixed results. Some TSRs and device drivers, for example, don't work properly if the the clock interrupt is reprogrammed. They use the counter you want to reprogram

Re: [Freedos-user] FreeDOS on SSD

Just as an FYI, USB flash drives (a.k.a. thumb drives, pen drives. etc.) do something similar but it's called wear-leveling instead of TRIM. In flash drives, though, it's all automatic (built into the hardware/firmware of the drive) and you never see it or interact with it directly. The flash

Re: [Freedos-user] Choosing an interrupt number

A well-written packet driver would do this all automatically for you and you wouldn't need to select an Interrupt number yourself. That is, if INT 0x60 wasn't already used (all zeroes in the Interrupt Vector Table or pointing at an IRET) it would automatically select 0x60. If 0x60 was used,
