Ever considered migrating it to Paradox 4.5 for Windows 3.1 instead? If it was discarded, I'd be curious to know more. The core db engine is supposedly the same.

TL;DR - is there a recipe to have packet drivers in a MVDM session talk to a NIC's physical device driver?

It works without any problems using FTP Software's PC/TCP with INT61VDD.SYS driver.


--- Quote ---Fast forward in 2025, I mostly only care about TCP/IP. While my previous searches led me to find some development material for "IBM TCP/IP for OS/2" (the vanilla TCP/IP support) there's really only very few applications designed around IBM's SDK beyond IBM's own tools or WinOS2 TCP/IP support.

The DOS part of the TCP/IP PTK shares the same interfaces with FTP Software's PC/TCP Version 4. So all TCP/IP DOS applications shipped with the PC/TCP product or OnNet should work.

I use Paradox 9 on Linux Wine almost daily for a couple GUI db apps, but I like Paradox for DOS if I just need to look things up via SQL as it's very fast.  PDX for DOS works fine in OS/2 when accessing SQL Server via db-lib, but I can't get to my Interbase data via Paradox for DOS in OS/2 as it requires FTP Software's FTP stack.  Not a big deal, but I had spent some time a while back to see if I could get it to work under OS/2, so I was interested in this thread. 

I couldn't find anything on that INT61VDD.SYS driver Bogdan refered to?

OMG, Bogdan... this is what I was looking for, and for a while now, but it seems that information was obliterated from the search engines.

The VDD must have a PDD counterpart? I assume this comes from PC/TCP for OS/2?

Sean Casey:
I see, that INT61VDD.SYS, an INT 61h emulator, was included in PC/TCP for OS/2.  I'll need to install both FTP Software's OS/2 and DOS products.

Update:  Installed PC/TCP OS/2 and DOS on Warp 3 and a quick test of the PC/TCP DOS stack seems to work fine.  Unfortunately, the version of FTP Software's PC/TCP for OS/2 version I have, version 1.3.1, isn't compatible with ArcaOS (INT61VDD.SYS dated 3/31/95).
