Seriously?  How is that possible?

That's the mod I am looking for.  I am sure I can hack the /t2 driver
to make multiple ports possible.

Be interested in that, as well as I thought the UART was single port.
If it's actuall dual port adding a MAX232 should be trivial.  Or
maybe use the second port to talk to my uDrive instead of hacking
the modme pak like I planned. :-)

I certainly don't remember anything like that when I was originally
doing CoCo.
