The cpm platform
=================
cpm is an i80-based BSP that generates CP/M executables that can be run on any
CP/M-compliant machine.
This port only implements a very limited set of syscalls --- and most of those
are stubs required to make the demo apps link. File descriptors 0, 1 and 2
represent the console. All reads block. There's enough TTY emulation to allow
\n conversion and local echo (but it can't be turned off).
There's a special, if rather minimilist, interface to give applications access
to CP/M. See include/cpm.h for details.
IEEE floating point is not available. Attempts to use floating-point numbers
will cause the program to terminate.
Example command line
====================
ack -mcpm -O -o cpm.com examples/paranoia.c
The file cpm.com can then be run.
(Although note that Paranoia is very big, and you'll need a CP/M machine with
lots of memory for it to fit. Which it does, just.)
