[Coco] Coco t2 driver

[edward jaquay]

On a real CoCo with RS232 Program Pak you would poke/peek $FF68 - $FF6B to
access the 6551 ACIA data, status, command, and control registers
respectively.  On Vcc there is no 6551 emulation so you can't do that yet.
I am looking into writing a dll for Vcc that allows it.  It plan to use a
tcp port for communications outside of Vcc.   But no promises as to how
soon it will happen. I am still learning how the ACIA is supposed to work.
Note that the drivewire program already provides similar functionality
using the becker dll.
