So far, I've been using this tool on remotes that had no control
character handling, but it doesn't work on a TRS-80 4P remote.

Much slower, but at least it works.

Later, I'll try to put some order in this so that we use the fast
lane when possible.

Previously, communications with my RC2014 would always be rocky and
fail most of the time. By sending an CR at init, things go much
smoother.

So far, I hadn't managed to run those tools properly on OpenBSD. I
was too confused by its stty peculiarities. I'm still confused, but
at least I managed to make them work... most of the time...

With this tool, we can send content to a TRS-80 directly to floppy.
This paves the way to writing ourselves a set of disks containing the
blkfs!

not actually tested yet...

By uploading a BASIC loop and then run it, we can reduce the serial
communication to pure content which greatly reduces the overhead and make
the process much much faster.
