You have a modem server? What do you do with it in this day and age?
We have one (well, 4, actually...) in work for claims transmissions from pharmacies using the antique versions of our software but I've not seen one outside of work in YEARS.
It was there to share a 'net connection through a firewall, before we got broadband, and I kept it there just in case broadband ever failed - which it didn't.
I'm going to clear it out this week, but there will be a small hole in my life where that P90 with 64 meg ram, (running redhat 6 i think) used to be.
