+.Sh NAME
+.Nm hsq
+.Nd
+multiplexing serial communications interface
+.Sh SYNOPSIS
+.Cd "hsq0 at isa? port 0x140 irq 10"
+.Cd "com* at hsq? slave ?"
+.Sh DESCRIPTION
+The
+.Nm hsq
+driver provides support for boards that multiplex together up to four
+.Tn EIA
+.Tn RS-232C
+.Pf ( Tn CCITT
+.Tn V.28 )
+communications interfaces.
+.Pp
+Each
+.Nm
+device is the master device for up to four
+.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 and the port for the interrupt multiplexing register.

+.Sh HISTORY
+The
+.Nm
+driver was written by Denis A. Doroshenko, based on the
+.Xr ast 4
+driver.
