Wow! It is a touch of master! Despite I prefer TASM conventions your code is much cleaner than mine. I like your use of AAM instruction :-) The only thing I think was better in my code was common procedure for converting number to string for both numeric systems :-/

Better would be to add switch "/A" for all ports. However this is not needed because you can call LPTtest from batch file for all ports. Are you really, absolutely sure that PC can't have LPT4? My eletronical manual about PC says (translation from czech): 0:040Eh - port LPT4, PS/2: Extended BIOS data segment BTW: My computer shows on 0:040Eh value 208h - it doesn't look as BIOS data segment, IMO > - tune delay handling further?

No. > - out baseport,4 should be re-enabled after somebody figures out how to check for ieee1284 printer presence before that Or we can add some command line switch "/C" (compatibility) ----- Original Message ----- From: "Eric Auer" <[EMAIL PROTECTED]> To: <freedos-devel@lists.sourceforge.net> Sent: Friday, July 13, 2007 5:22 PM Subject: Re: [Freedos-devel] LPTtest v1.3 > > Hi all, > > > I added help screen, possibility to scan other LPT ports and a little > > modyfied delay routine.
