-.Sh NAME
-.Nm tw
-.Nd TW-523 X-10 device driver
-.Sh DESCRIPTION
-.Nm Tw
-is the driver for the TW-523 power line interface, for use with X-10 home
-control products.  The X-10 protocol is compatible with a number of home
-control systems, including Radio Shack ``Plug 'n Power(tm)'' and
-Stanley ``Lightmaker(tm).''
-.Pp
-The driver supports
-.Fn read
-.Fn write
-and
-.Fn select
-system calls.
-The driver allows multiple processes to read and write simultaneously,
-but there is probably not much sense in having more than one reader or more
-than one writer at a time, and in fact there may currently be a race
-condition in the driver if two processes try to transmit simultaneously
-(due to unsynchronized access to the sc_pkt structure in tw_sc).
-.Pp
-Transmission is done by calling
-.Fn write
-to send three byte packets of data.
-The first byte contains a four bit house code (0=A to 15=P).  The second byte
-contains a five bit unit/key code (0=unit 1 to 15=unit 16, 16=All Units Off
-to 31 = Status Request).  The third byte specifies the number of times the
-packet is to be transmitted without any gaps between successive transmissions.
-Normally this is 2, as per the X-10 documentation, but sometimes (e.g. for
-bright and dim codes) it can be another value.  Each call to
-.Fn write
-can specify
-an arbitrary number of data bytes, but at most one packet will actually be
-processed in any call.  Any incomplete packet is buffered until a subsequent
-call to
-.Fn write
-provides data to complete it.  Successive calls to
-.Fn write
-leave a three-cycle gap between transmissions, per the X-10 documentation.
-The driver transmits each bit only once per half cycle, not three times as
-the X-10 documentation states, because the TW523 only provides sync on
-each power line zero crossing.  So, the driver will probably not work
-properly if you have three-phase service.  Most residences use a two-wire
-system, for which the driver does work.
-.Pp
-Reception is done using
-.Fn read
-The driver produces a series of three
-character packets.  In each packet, the first character consists of flags,
-the second character is a four bit house code (0-15), and the third character
-is a five bit key/function code (0-31).  The flags are the following:
-.Bd -literal
-#define TW_RCV_LOCAL	1  /* The packet arrived during a local transmission */
-#define TW_RCV_ERROR	2  /* An invalid/corrupted packet was received */
-.Ed
-.Pp
-The
-.Fn select
-system call can be used in the usual way to determine if there
-is data ready for reading.
