real-mode trap files

[Baron-von-Riedesel]

Hello,

Currently I try to make a trap file for HX that worked with OW 1.9, to also work with OW 2.0. But it looks like no real-mode trap file works in current v2.0, AFAICS.

The trap helper file for HX can write a log, where one can see what requests are send. It's strange, because it begins so:

Rqst: READ_FPU
Rqst: 0F 00 64 6F 73 31 2E 65 78 65 00 00               ..dos1.exe..

Error: 00

In OW v1.9, the log usually begins with a LOAD_PGM

Rqst: PROG_LOAD
Rqst: 14 00 00 00                                       ....

Rply: 00 00 00 00 00 00 00 00 00 00 00 00 00            .............

Rqst: GET_SYS_CONFIG
Rqst: 06                                                .

Rply: 31 31 07 0A 07 0C 01                              11.....

Rqst: GET_SYS_CONFIG
Rqst: 06                                                .

Rply: 31 31 07 0A 07 0C 01                              11.....

Rqst: READ_REGS
Rqst: 24                                                $

So there is really something messed up...

Ok, the mystery is solved: in v2.0, there were a few functions removed from the trap call vector: REQ_READ_CPU, REQ_WRITE_CPU, ...

After adjusting this, the hx trap file works with v2.0.

There are a few issues in WD ( in this context, it's always the DOS version I'm talking about), though:

• ESC "doesn't work" ( you can't close a dialog or menu by pressing ESC, for example )
• the cursor doesn't move in the source window ( so to set a breakpoint, you have to switch to the assembly window )
• no page flip or screen swap when F10 ( step over ) is pressed ( F5 works, though ).
• when the debugger stops at main(), the source window is empty ( pressing F6 "fills" it! )
