Score one for the 3270 emulation. I worked for a small company in the mid 90s whose software was used to connect to the mainframes that airlines used for scheduling. We provided software that allowed for dial-up access to those systems from home (among other things). The core software was built in Delphi and was basically a dialer married to a 3270 emulator.
