Okay, the issue was the handling of the Write Error Code command. It should
now satisfy all of those criteria. It should now restore the cursor position
after the error code per spec, although the spec is a little vague in one
case, and it now inhibits. Actually, it no longer uninhibits the display when
it receives the next command from the host.

Some are, some aren't. The host sends coordinates 1-based, we handle them
internally 0-based (it makes our math much easier).

FYI, '@eor' punctuates a group of '@record's, if you delete the @records,
delete the @eor - otherwise the emulator complains that it received a 0-byte
record :)
Expect changes to CVS shortly (after I handle some other bugs)... maybe a
release, who knows...
