An Amiga developer friend, John Foust, late of the net, gave this to
me to post.
This is the IBM to Amiga text filter. It translates stdin to the hex
stream that AmigaDOS "READ" needs, expanding TABs to spaces, ignoring
CR, and passing LF.

/*
toamiga.c
A program to transfer ASCII files from a IBM PC to the Amiga,
for use with the Amiga READ command.
This filter ignores CR, passes LFs, and expands TABs to spaces.
Stdin should be a ASCII text file.
Stdout gets a stream of hex nybbles, with end of stream marked by 'Q'.
V1.0: John Foust, October 26, 1985 with Lattice C v2.15 under PC-DOS.
This is public domain software. If want to send me money, go for it.
