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

3fa044c149 Implement support for int2f/ax=1220. 
Fix int2f/ax=1216 (needs sft handles, not psp handles, and to return
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 #.

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.
