I am running CP/M 2.2 on a TRS-80 with the OKIDATA modification (so that
"vanilla" CP/M code will execute unmodified).  At present I'm trying to
bring up a small-C compiler and it needs primitives for getchar() and
putchar().  Surely someone has solved this already.  What's the easiest
way to do this -- calls to the BIOS? -- to BDOS?  -- custom code? 
All solutions will be appreciated.  As usual, sufficient interest will
produce a summary to net.micro.cpm
