Subject: Re: Dos App hangs with DPMI / PIC problem
Date: Fri, 17 Sep 2004 04:18:34 +0000	[thread overview]
Message-ID: <BAY15-F36tNTlwKg7Bj000c8d05@hotmail.com> (raw)



Hello,

1.  Tried
>e c316:903a EB
>e c316:903b 08

the trace becomes different, but the app still hangs...

2.  Also tried using freedos instead of msdos.  Same thing...

BTW, the app is actually a client - server app running on netx.  Not sure if 
this is relevant...

Thank you, everyone, for helping out!
