d17f333243 From Lucho (and I think Arkady had this as well at some point): 
save 33 bytes by eliminating a switch for memory/UMB access modes.

69faceffe5 int21/ah=26: new_psp now copies the old psp and just sets a few fields 
int21/ah=55: child_psp does the rest
init code does the init (fixed values are always copied now)

0e0abcd685 Added explicit (UWORD) type casts to avoid compiler warnings and sometimes 
save a few bytes too. Also changed the FcbParseFname return value:
returns offset portion of pointer (SI) instead of the number of bytes to
be added to SI.

b7491eba32 Expand tabs for int21/ah=2,9 even in raw device modes and if stdout is 
redirected. This solves bug 1737 (grep2msg problem)
This copy&paste exercise is to be cleaned up a bit later!

3fa044c149 Implement support for int2f/ax=1220.

the relative handle in BX, and to deal with carry)

bdc5569995 Set the Critical Error number immediately after calling a device driver. 
This solves problems with int24 handlers that call int21/ah=59.
Let truename and blockrw return with an error if there is a critical error.
Don't overwrite the critical error # with the DOS error #.

b0e54ff704 (with a little help from Arkady) 
inthndler.c, chario.c, break.c simplifications and cleanups.
Pass a near pointer to the far pointer that points to the device instead
of an SFT index (in general).
Make cooked_write much faster by only testing for input every 32
characters.
No longer test for ctl_s on syscon if writing to the printer: just
read from the printer which will return zero characters.
Fix reading/writing zero characters by returning "256" (special code).
Adjust interfaces in other files.

756c578ca7 (joint with Luchezar Georgiev): add extra low disk buffer to avoid HMA 
problems with certain device driver. Add an extra space for the device
driver command line and point to a correct environment for
INSTALL= (fixes problems with xmsdsk).
