Hey Andrew!

Ouch.  I don't envy you any, especially the surgery part.  As for programming,
I swore off of GUI progamming after writing a printer driver for Win-3.1 way
back in the day.  I've lived up to that oath ever since which makes it about
30-ish years.

Sounds like a plan.  Everything will keep in the meantime I am sure.

Consider it bookmarked.  :-)

 AA> Also I took over as maintainer of the abandoned modemu project

That sounds familiar.  If I am not mistaken I first heard about it back in
1995-ish perhaps a year or two later.  I last had a working modem (external)
around then so something like that would have gotten my attention.

Also bookmarked.  I'll check it out later as you've got my curiousity aroused. 
I am not sure at this stage of the game I'd be keen to use a modem emulator on
minicom.  The last time I played with minicom was to output raw GPS sentences
from a usb GPS reciever about 15-ish years ago.  I still have the reciever but
last time I played with it was with gpsd.

Life is good,
Maurice
