Properly Configuring Terminal Emulation in Unix?

Jobe_br asks: "I've recently come across a need for a way of connecting to a SCO Unix box with full SCO-ANSI emulation (so that I can send F1-F12 commands and ASCII line art appears as lines, not strange foreign letters). After checking out the Terminal-HOWTO at linuxdoc.org I came away with no clearer understanding of what I need to do. I can pretty much pick any 'ole terminal emulator for win32 and get what I need, but no matter what I do to fiddle with my xterms/eterms/vts I can't get things to go. Is this not facilitated under Linux?"
