.Dd July 23, 1995 .Dt MFCS 4 amiga .Os .Sh NAME .Nm mfcs .Nd .Tn BSC/AlfaData MultiFaceCard II/III serial communications interface .Sh SYNOPSIS .Cd "mfc0 at mainbus0" .Cd "mfcs0 at mfc0 unit 0" .Cd "mfcs1 at mfc0 unit 1" .Sh DESCRIPTION The .Tn MultiFaceCard II/III controls, among other things, a dual port .Tn EIA .Tn RS-232C
f ( Tn CCITT .Tn V.28 ) communications interface with a multiple character buffer.
p 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.
p 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. .Sh FILES l -tag -width Pa t Pa /dev/ttyA? .El .Sh DIAGNOSTICS l -diag t mfcs0: fifo overflow. The four-character input .Dq fifo has overflowed and incoming data has been lost. t mfcs0: %d buffer overflows. The software based input ring buffer has overflowed %d times and incoming data has been lost. .El .Sh SEE ALSO .Xr tty 4 .Sh HISTORY The .Tn Amiga .Nm device first appeared in .Nx 1.1 .Sh BUGS The MultiFaceCard II/III serial ports use the level 6 interrupt and may experience fifo overflows if the LEV6_DEFER option is used.
