+.Os
+.Sh NAME
+.Nm tncd
+.Nd create a KISS TNC from an AX.25 interface
+.Sh SYNOPSIS
+.Nm
+.Ar patty.sock ifname
+.Sh DESCRIPTION
+.Nm
+exposes a
+.Xr pattyd 8
+interface as a KISS TNC via a pseudoterminal.  This device can either be read
+from or written to.  The device can be connected to by only one process at a
+time.  However, multiple instances of
+.Nm
+can be attached to an interface simultaneously.  Each frame sent out to the
+interface, or received by the interface, is written to the KISS TNC device.
+In turn, each frame received by the KISS TNC is sent out to the interface.
+.Pp
+Both arguments,
+.Ar patty.sock ,
+a Unix domain socket to a
+.Xr pattyd 8
+instance, and an
+.Ar ifname ,
+an interface valid on that AX.25 daemon, are required.  When a KISS TNC
+device is successfully created, the pseudoterminal device name is printed to
+standard output.
