+.Sh NAME
+.Nm ioat66
+.Nd
+multiplexing serial communications interface
+.Sh SYNOPSIS
+.Pp
+For 6-port BOCA IOAT66 board:
+.Pp
+.Cd "ioat0   at isa? port 0x220 irq 5 
+.Cd "com2    at ioat? slave ?"
+.Cd "com3    at ioat? slave ?"
+.Cd "com4    at ioat? slave ?"
+.Cd "com5    at ioat? slave ?"
+.Cd "com6    at ioat? slave ?"
+.Cd "com7    at ioat? slave ?"
+.Sh DESCRIPTION
+The
+.Nm ioat66
+driver provides support for BOCA Research IOAT66 
+boards that multiplex together up to six
+.Tn EIA
+.Tn RS-232C
+.Pf ( Tn CCITT
+.Tn V.28 )
+communications interfaces.
+.Pp
+Each
+.Nm
+device is the master device for up to six
+.Nm com
+devices.  The kernel configuration specifies these
+.Nm com
+devices as slave devices of the
+.Nm
+device, as shown in the synopsis.  The slave ID given for each
+.Nm com
+device determines which bit in the interrupt multiplexing register is
+tested to find interrupts for that device.
+The
+.Tn port
+specification for the
+.Nm
+device is used to compute the base addresses for the
+.Nm com
+subdevices. The port for the interrupt multiplexing register is not
+programmable.
