[Coco] Bit-Banger Serial as external console?

[Arthur Flexser]

If the code is position-independent, there's no need to reassemble it.
Just load it in to wherever you want it using an offset, and resave it
there.  For example, if it is currently at $3F00 and you want it at
$2000, try LOADM"REMOTE",&H2000-&H3F00.

I went ahead and gave it a try, but of course that does not work because the REMOTE driver (as published) sits in the middle of one of Color Forth’s screen buffers.  When I invoke Color Forth, the remote terminal connection disappears, probably because the screen buffers are initialized in some way.

I loaded in EDTASM so I could use the ZBUG to type the bytes in again, but I found that after I typed in several bytes, ZBUG crashed, so I must have been typing right into the memory being used by EDTASM - DOH!
