moved a few rmod init routines to a common asm block
1877
54 d 12 h
mateusz.viste
/svarcom/trunk/
dropped origenvseg from rmod + copying the initial (kernel) environment, if found
1863
56 d 12 h
mateusz.viste
/svarcom/trunk/
SvarCOM provides its own INT 24h handler
1847
60 d 11 h
mateusz.viste
/svarcom/trunk/
computation of COMSPEC offset should be more robust now
1730
235 d 3 h
mateusz.viste
/svarcom/trunk/
implemented the internal LOADHIGH command
1597
320 d 11 h
mateusz.viste
/svarcom/trunk/
save (and restore) the original parent of my PSP as advised by E. C. Masloch
1595
321 d 5 h
mateusz.viste
/svarcom/trunk/
set parent of transient SvarCOM to RMOD (apparently required by EDR-DOS?)
1594
321 d 6 h
mateusz.viste
/svarcom/trunk/
preserving bx,cx,dx registers throughout inline assembly block
1591
324 d 5 h
mateusz.viste
/svarcom/trunk/
instead of raw-copying a PSP for RMOD, ask DOS to generate it via int 21h,ah=26h
1590
324 d 13 h
mateusz.viste
/svarcom/trunk/
do NOT close file handlers in an attempt to preserve the stdin/stdout/etc descriptors
1589
324 d 14 h
mateusz.viste
/svarcom/trunk/
RMOD's PSP set so the SS:SP pointer has some room to POP things (advised by E. C. Masloch, thanks\!)
1588
324 d 17 h
mateusz.viste
/svarcom/trunk/
preset RMOD's JFT size to 20 slots (which is the maximum that the PSP can hold - more than this would require a separate allocation)
1587
325 d 4 h
mateusz.viste
/svarcom/trunk/
patching up RMOD's PSP once it is loaded in memory: clearing out the JFTand presetting a stack address. thanks to E. C. Masloch for pointers
987
952 d 19 h
mateusz.viste
/svarcom/trunk/
improved stack overflow protection so it is allows stack overflow as long as it does not touches actual data
983
953 d 7 h
mateusz.viste
/svarcom/trunk/
smart stack overflow detection: damages only the commandline history and degrades gracefully
975
955 d 3 h
mateusz.viste
/svarcom/trunk/
transient shell follows the int23h vector to locate RMOD (LINK/LN compatibility workaround)
963
955 d 7 h
mateusz.viste
/svarcom/trunk/
rmod bat ctx linked list is freed using a specialized function to enable reusability
957
956 d 4 h
mateusz.viste
/svarcom/trunk/
CALL support for calling batch files from within batch files
949
956 d 13 h
mateusz.viste
/svarcom/trunk/
redesign of how batch contexts are stored in memory (required for future CALL support)
537
1046 d 5 h
mateuszviste
/svarcom/trunk/
added break handler
479
1053 d 7 h
mateuszviste
/svarcom/trunk/
cmdline far ptr is replaced by a local array, shared with BUFFER and merged with rmodcore
478
1053 d 12 h
mateuszviste
/svarcom/trunk/
renamed rmod array to rmodcore and removed its const flag so the memory can be possibly reused for other purposes
475
1053 d 14 h
mateuszviste
/svarcom/trunk/
rmod->echoflag merged inside rmod->flags
465
1055 d 7 h
mateuszviste
/svarcom/trunk/
rmod stacking is possible (multiple command.com instances) + minor optimizations
459
1056 d 6 h
mateuszviste
/svarcom/trunk/
rmod has a PSP now
454
1056 d 17 h
mateuszviste
/svarcom/trunk/
simplified rmod_install()
453
1056 d 18 h
mateuszviste

saving original env seg in rmod so I can detect "I am process 0" situations in MS-DOS 5/6
450
1057 d 9 h
mateuszviste
/svarcom/trunk/
moved some data into rmod props struct
449
1057 d 12 h
mateuszviste
/svarcom/trunk/
implemented /P and a generic rmod memory buffer for transient-only settings
448
1058 d 8 h
mateuszviste
/svarcom/trunk/
each svarcom instance has its own rmod + svarcom is able to quit (unloading its rmod in the process)
439
1060 d 10 h
mateuszviste
/svarcom/trunk/
use env_lookup_val() when possible
421
