NAME
     mfcs - BSC/AlfaData MultiFaceCard II/III serial communications interface

SYNOPSIS
     mfc0 at mainbus0
     mfcs0 at mfc0 unit 0
     mfcs1 at mfc0 unit 1

DESCRIPTION
     The MultiFaceCard II/III controls, among other things, a dual port EIA
     RS-232C (CCITT V.28) communications interface with a multiple character
     buffer.

     Input and output for each MultiFaceCard III line may set to a maximum
     baud rates of 1152000.  Formula for baud rate:  Baud = 230400 / N with 1
     < N < 65536.

     Input and output for each MultiFaceCard II line may set to a maximum baud
     rates of 57600.  Formula for baud rate:  Baud = 115200 / N with 1 < N <
     65536.

FILES
     /dev/ttyA?

DIAGNOSTICS
     mfcs0: fifo overflow.  The four-character input ``fifo'' has overflowed
     and incoming data has been lost.

     mfcs0: %d buffer overflows.  The software based input ring buffer has
     overflowed %d times and incoming data has been lost.

HISTORY
     The Amiga mfcs device first appeared in NetBSD 1.0A

BUGS
     The MultiFaceCard II/III serial ports use the level 6 interrupt and may
     experience fifo overflows if the LEV6_DEFER option is used.
