I sent that code all off to Steve Odneal (porter of Dyancomp Flex to
the COCO, and author of Kansas City Basic, as well as the PRO/SCR hard
disk hardware and software) and he got MOST of it going, but even with
a public domain Macro assembler I sent him, he still has a LOT of work
to do an turning it into a relocatable macro assembler, which a C
compiler requires. Overall, you ARE better off with the MW compiler
(at least IT exists!). Build a minimal bootfile with no RS-232 stuff
(or no CCIO stuff, if using a remote tube), no printer, no pipes - no
non-essentials for the edit/compile cycle). Also, the level II coco
III will relieve your memory problem (512K is a MUST).

I have a primitive little package that talks to the OLD cassette port
attached PNP controller.. works great, and I could mail you source if
you like. However, 'PAK' software was never written under OS9. I
believe that there were some routines written up under RS-DOS
assembly language that handle the pak. This might be enough to get you
started.

Also, there is some unix-based code called X-10 that was posted a
while back that supports the RS-232 based  'X-10 Powerhouse Controller'. 
I bought one of these on a closeout from DAK for $19.95 (;^) a while back. 
I have yet to complete the port (I work on it occasionally). It looks
like the OS9 port will be RELATIVELY painless.

Re: the RAW mode... sure.

a) Use i$read/i$write vice using i$readln/i$writln (BASIC09 get/put
instead of input & print).

b) Turn off the appropriate path options by getting 2 copies of the
path descriptor option section (32 bytes) using the i$getstt call,
diddle the appropriate bytes (zero the bytes for QUIT and ABORT to
prevent operator interrupts, for instance - see the DEFS files and
look for the PD.??? for more detail), then send the diddled version
back to the path with an i$setstt. When you're done mucking about,
send the virgin copy back to restore the previous state.
