and let it return a long instead of using a *err pointer.
Call the resulting function NETWORK_REDIRECTOR_MX (multiplex)

Seems to be more consistent now. read_char_sft_dev handles ^C at a fairly
high level. So raw_get_char doesn't need to worry about sft's anymore.

- ^C didn't work for int21/ah=3f. Corrected -- Do_DosIdle_loop still needs
to wait even if it doesn't call the idle int
- ^C needs to be echoed to STDOUT for low character functions (ah<0xd) but
to the device that is read from for handle functions. So we need to pass
either the STDOUT sft or that device on to the ^C echoer.
- The ^C echo really should print ^C\r\n.
- misc cleanups in break.c.

them pop the stack (smaller code than using bx).
Tell Watcom which registers are clobbered; save some more registers
for intr() -- especially for intr() this helps.

all other compilers can use it with pascal or "register" calling conventions.
Saves ~50 bytes for the init code.

Internally the kernel uses two near fnodes though, to save on codesize
and fmemcpy's if necessary. Having memory management on two fnodes is
a little silly but I just want to make sure with the panic message
that we never accidentally try to use three near fnodes at the same time.
(two are used at the same time by rename, commit, and merge_file_changes).
This can be cleaned up later.
Anyway. 644736 bytes free conv memory isn't bad.

FAT16 partitions (just like FAT16 kernels do)
* added extra checks to make sure that invalid FAT entries are never
followed
* made put_console() public to be able to print a message in case of
FAT corruption
* some small optimizations and header cleanups (some suggested by Arkady)

Fix int2f/ax=1216 (needs sft handles, not psp handles, and to return
the relative handle in BX, and to deal with carry)

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 #.

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.
