I just ran Ultimaterm, and it DOES work — I type blind, but it works.

That’s what I want.

But Greg-E-Term seems to not let me do anything.

So it’s software controlled?

In Ultimaterm, as soon as I drop DCD, I can still type and see TX/RX and see lights blink as Zimodem sends responses, it just doesn’t show up.

But in Greg-E-Term, no DCD means it doesn’t even send, apparently.

I’ve been using GETerm primarily because I thought it was be a good “lowest common denominator” test… Something that works on a CoCo 1, 2 or 3.

So what’s the scoop on GETerm? Do others work like this?
