  Not too painful... I wrote one a few years ago which was called from C
with the address of a buffer and the length. At each interrupt the
character was put into the buffer. Another asm routine returned a char
to the C program. The whole thing was only a few hundred bytes.

  Before you ask, it's still considered proprietary and I can't send you
a copy. I asked before I posted.
