[Solved] Target Go32v2 DOS - How to implement COMPORT (possibly FOSSIL support?)

[Ozz_Nixon]

I have code from TP7 DOS days (QModem from John Freil), that I would like to use GO32 Target - and thus, port it to 32bit Console (Using XP 32bit)/DOSBox-X exe.


I am not totally familiar with how GO32v2 actually works. Could someone point me to how to implement COMPORT support? The existing source uses Fossil and BIOS communications - I did not try to compile those two, as I remember in BP7 DPMI mode, things broke. (Am I to assume GO32 is going to do the same for everything?) - my goal is to walk the source up to eventually native FPC Win32 exe.

PS. Is there a URL that steps through setting up i8086 Target (e.g. cross-compiler, I assume)?


Thanks for any insight!

my goal is to walk the source up to eventually native FPC Win32 exe.

It might be easier to go to Win32 or Win64 right away considering that there's a Serial unit. Cause the step will be big either way no matter if you go from i8086-msdos or i386-go32v2.

This might help.

@PascalDragon... thanks for the *This* link. It answered my next set of questions.


Per jumping to Win32 or Win64 ~ I author DXSock suite, so, I will be using my own Sockets. [Which have been FPC friendly since FPK days]. ;-)


PS. I also author:
1)   DOS Pascal - a 99.9999% clone of Turbo Pascal 7.0
2)   Modern Pascal - a 32/64bit p-code script engine (for every platform FPC is available - as it's my bootstrap).
3)   Most-Recently:
          Little Open Source Multi-Language Compiler ~ Los Compiler. (Compiles Pascal, Basic and C to DOS, Win32 and Linux32).
          Patched XD Pascal - to support Objects, Classes and much more.



So, I understand challenges, legacy development - and since I have brain cancer ~ cannot find an employer ~ I focus on porting all BBS source I can get my hands on to 16/32/64bit.
