OK, I'm programming this little serially-controlled gadget, and
talking to it direct-connect RS-232, through Hyperterminal. Ht is set
up in asr-33 tty mode, bog simple. The box is spitting out plain ascii
text.
There's a white box on the screen that shows my current conversation
with El Gadget, and it all looks right. But the "backscroll buffer",
the grey stuff above which shows older text, tends to be garbled, even
though it rolled out of the white box correct. And there are snippets
of really old text stirred in.
Ok, so everything is working normally.....
Why?
Cuz you used hyperterminal.
And once I managed to aim a pointer at code instead of text (it would
be impolite to ask) so my box actually shot out binary glop. So Ht
printed junk on the screen, fair enough. But after that it also
garbled local echo text! WTF?
Oh, wait, I figured out what's wrong:

Exactly. I use PUTTY. It's free and it works, what more can anyone ask?
I tried Putty, but it's about as weird as Hyperterminal, except that
Putty is Unix weird, and Ht is Windows weird.
It was handy in that I right-clicked the mouse and it sent something
truly weird to my box - can't figure out exactly what - and my box did
something it's not supposed to do, so that's a good thing to know.
All I want to do is type, have the chars go to my box, and display
what comes back. That's not a lot to ask, is it?

Get some old PC (like a Intel Quad 3.4 GHz LOL), and install Linux.
I run minicom 24/7 on one for example.
Minicom is OK (but not perfect).
But is is OK to test embedded systems.
It also has zmodem, xmodem, ymodem, kermit protocols.
And you can have configure files for each system,
minicom my_embedded_system
will start it up fully configured for my_embedded_system.
No idea why anyone still puts up with MS wing clipped stuff.
All you need as a new HD and 10 minutes to install something like
Debian or, like I use grml (but grml is for nerds, better try Debian first).
