Hello,

I seem to have misplaced my TT schematics and Google hasn't
helped me find them on the Web.  :-/

I've been laying awake at night wondering which serial ports
on a TT are wired to which chip.  A quick trawl through the
port-atari archive suggests the following...

  Labeled   Old device  New device  Chip     Notes
  ~~~~~~~   ~~~~~~~~~~  ~~~~~~~~~~  ~~~~~~~  ~~~~~~~~~~~~~~~
  Serial2   /dev/ser02  /dev/tty00  8530 A   Also LAN port?
  Modem2    /dev/mdm02  /dev/tty01  8530 B
  Modem1    /dev/mdm01  /dev/tty02  1st MFP
  Serial1   /dev/ser01  /dev/tty03  2nd MFP  Missing lines?

            ...could someone confirm or correct this for me?
I would also be interested in knowing what kind of through-
put to expect from each port.

Does anyone here happen to know which signals are missing
from Serial1?  I was looking at a MegaSTE schematic last
night, which seemed to have the DSR input (pin 6 on a DB9)
not connected.  Perhaps the TT's Serial1 is more severely
limited?
