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
