serial port mapping
===================

Every driver support two devices for each port, one HSMODEM device
and one Unix terminal device.

HSMODEM devices use the traditional Atari port names. UNIX terminal devices
are always called ttyS followed by a number:

port names on the machines:

modem2   ttyS1      -       MODEM2    MODEM2    MODEM2   unknown   UART1 (2f8)
serial1  ttyS2      -       -         SERIAL1   -        unknown   -
serial2  ttyS3      -       SERIAL2   SERIAL2   -        unknown   UART2 (3f8)
lan      ttyS4      -       LAN       LAN       LAN      unknown   -
midi     ttyS5      Midi    Midi      Midi      Midi     unknown   -


NOTE:  Serial2 and LAN are mutually exclusive, on the MegaSTE and
       TT; selecting Serial2 disables LAN and vice-versa, because
       they both use SCC-A
