Connecting SIMH to teletype via USB

[Charles]

I got ahead of myself a little bit... forgot I still couldn't connect a 
serial port to SIMH.

Turns out my version of SIMH 3.08 was from 2008 or so... I just downloaded 
the latest version 4 from GitHub and sure enough it does accept SET CONSOLE 
SERIAL.
Now I just have to figure out the port name since it doesn't like COM4:
But I'm almost there :)

Update: got my SIMH (set console telnet:23) talking to PuTTY in another
window, via Telnet 127.0.0.1:23.
So it is possible ;)
Now it's time to hook up the actual TTY to the USB-current loop card and see
what's what!

Section 3.14, "Console Options" of the "SIMH Users' Guide V4.0" suggests
that:

  set console serial=com4;110-8n2

...should work (though you might need "7e2" or "7o2" instead, depending on
how your Teletype is set up).

Does the above also give this error?
