Has anyone gotten either of these to work right under AT&T's SysVr3?
Pcomm compiles OK but there is a problem with the screen positioning
on the console and I'm not sure if it works with modems that don't
keep carrier detect up all the time - it doesn't on a 3B2, anyway.

What's the latest release/patch level for these?
