VOILA! -> TERMINAL-fx v0.1
TERMINAL-fx is a terminal emulator for the fx-9860 that allows your fx-9860G to communicate simultaneously with another calculator or the PC (or any device that is capable of serial input/output). Transmission and reception occur simultaneously allowing great interaction.
I've tested it against my PC using a FXI cable. Works perfectly (click for larger image):

Here's the communication format:

Calc <-> calc: Working? - Not yet tested
Calc <-> PC: Working

Source code: Coming soon!!! - After I push out Rev-FX v0.3. I'll be updating the site documentation soon.

Bug findings, comments and suggestions are welcome.
BTW: If anyone is interested, while working on TERMINAL-fx, I've calculated the actual speed of the fx-9860G's CPU: 14.74MHz. Lower than what I expected. But then that means according to those calculator benchmarks by Xerxes, the fx-9860G's SH3 CPU @58.96MHz pwned the HP-50's ARM CPU @75MHz.
