This sounds like a library problem: read.s, the source file for the read()
function of the C-library, was not DPMI-compatible in some earlier version.
This has been fixed quite some time ago, and there was a small utility called
dpmifix that could fix it in readily linked executables by binary patching.
So: check if you have a correct version 1.12m3 (or m4) installation, and
esp. a correctly patched libc.a (did you run the *.bat files included in
112m[1-4].zip? they are there to patch the libc.a). 

Hope this helps a bit
