Which are all important.  I do not appreciate bugs that cause me to
lose data.  On the other hand, I am also a software author and I *do*
understand just how easy it is to botch things.  I just do not
appreciate seeing buggy software released.

And why can't I give Geoff a rough time?  It's almost fun to ruffle
him a little.  ;-)

DEC always did have interesting manuals.

]Perfect emulation isn't really needed, the full VT100/102 command set

I'm not asking for dh/dw characters.  I'm also not asking for LED
status indicators (especially when the basics are still buggy).  If my
local UNIX can know where my cursor is at all times, I will be happy.
This is not a heck of a lot to ask when using error correcting modems
on both ends.

In other words, I agree.

On the other hand, the more implemented, the better.  I have vt100
termcap entries that will make my visual editor crawl because certain
features are not listed as "implemented," and others that implement a
few "special" features and make things fly.  But only if the emulator
emulates them.  :-)

]P.S. I'm not really trying to "push" my own terminal. I don't
]distribute it, nor do I think it's a perfect VT100 termnial, it's just
]a programme I wrote because there is nothing for a 64 with a BI-80.

What do you call C64KERMIT?  It works very well with a BI-80, thank
you very much (and I wouldn't try a VT100 emulation on a 64 without
it, although KERMIT does an admirable job trying.... just can't keep up).


By the way, has anybody successfully make c64kermit run at 2400bps?
