What parts are undocumented? All of them are pretty clear to me.

(all) modem1 modem1 ...19200 hardware MFP
Falcon modem1 n/a ...19200 hardware MFP
TT modem2 modem2 38k4,76k,153k hardware SCC
MEGA-STE modem2 modem2 38k4,57k6,115k2 hardware SCC
Falcon modem2 modem 38k4,57k6,115k2 hardware SCC
TT serial1 serial1 ...19200 software MFP-TT
MEGA-STE/TT serial2 serial2 38k4,57k6,115k2 hardware SCC
M-STE/TT/Falcon serial2 LAN 38k4,57k6,115k2 software SCC
1) serial1 only has TX and RX, no handshake lines.
2) serial2 has all the control lines as modem2, except CD.
3) LAN and Serial2 share the same half of the SCC and are mutually
exclusive. LAN is selected by default, on bootup.
4) HS-Modem's SCC driver allows both "lan" and "serial2" to be present,
but both ports are still mutually exclusive. Selecting either device
automatically disables the other.
Traditionally, those device names are symlinked as follow:
modem1 = ttya
modem2 = ttyb
serial1 = ttyc
serial2 = ttyd
midi = ttye
That particular list comes from the KGMD choices made by Knarf.
PS: I personally use the original GEMDOS device names, because
using tty names is about as cryptic as it gets. Human-
readable device names are more user-friendly.
