0694ff1acb (from Lucho) Remove AL=0 check for AH=6c 
(from Arkady) Optimize DL check.

a0f4465045 From Eric Luttmann: 
fix for multi-segment device drivers; preserve rq_endaddr between init
calls for the same driver.

8db46073f9 From: Eric Luttmann <ecl@users.sourceforge.net> 
Fix for multisegmented device drivers: If there are multiple device
drivers in a single driver file, only the END ADDRESS returned by the
last INIT call should be the used.  It is recommended that all the
device drivers in the file return the same address.
This fixes a load problem with DUSE.

61d87d82bb Rename the global lpFcb variable to sda_lpFcb. Then use local lpFcb 
variables where necessary. This clears up the confusing shadowing.

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 #.

2f4e2d3a69 * add support for the far jmp at "int 30" (0000:00c0) 
* mirror it for the HMA (ffff:00d0)
* put all DOS int handler (and the CPM entry jumped to from int30)
  jumpers in the "CONST" portion of DGROUP (instead of LGROUP)
  This helps Turbo C++ 1.01 make with the -S (swap) switch.
* adjustments to set the relevant PSP fields in task.c

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.
