Subject: socz80: get init as far as fork()
X-Git-Url: https://git.ndcode.org/public/gitweb.cgi?a=commitdiff_plain;h=757d39b7200127ba7f8dcf90094aa12f78c1ee7f;p=FUZIX.git

socz80: get init as far as fork()

This gets init as far as fork(). As the fork code hasn't been written yet it
dies there.

tty is polling for tx ready - until I figure out why the IRQ bits are broken
