L-DEVICES(5)	    UNIX Programmer's Manual	     L-DEVICES(5)


NAME
     L-devices - UUCP device description file

DESCRIPTION
     The L-devices file is consulted by the UUCP daemon uucico(8)
     under the direction of L.sys(5) for information on the dev-
     ices that it may use.  Each line describes exactly one dev-
     ice.

     A line in L-devices has the form:

     Caller  Device  Call_Unit	Class  Dialer  [Expect	Send]....

     Each item can be separated by any number of blanks or tabs.
     Lines beginning with a `#' character are comments; long
     lines can be continued by appending a `\' character to the
     end of the line.

     Caller denotes the type of connection, and must be one of
     the following:

     ACU     Automatic call unit, e.g., autodialing modems such
	     as the Hayes Smartmodem 1200 or Novation ``Smart
	     Cat''.

     DIR     Direct connect; hardwired line (usually RS-232) to a
	     remote system.

     DK      AT&T Datakit.

     MICOM   Micom Terminal switch.

     PAD     X.25 PAD connection.

     PCP     GTE Telenet PC Pursuit.

     SYTEK   Sytek high-speed dedicated modem port connection.

     TCP     Berkeley TCP/IP or 3Com UNET connection. These are
	     mutually exclusive.  Note that listing TCP connec-
	     tions in L-devices is superfluous; uucico does not
	     even bother to look here since it has all the infor-
	     mation it needs in L.sys(5).

     Device is a device file in /dev/ that is opened to use the
     device. The device file must be owned by UUCP, with access
     modes of 0600 or better. (See chmod(2)).

     Call_Unit is an optional second device file name.	True
     automatic call units use a separate device file for data and
     for dialing; the Device field specifies the data port, while
     the Call_unit field specifies the dialing port.  If the

     Call_unit field is unused, it must not be left empty.
     Insert a dummy entry as a placeholder, such as ``0'' or
     ``unused.''

     Class is an integer number that specifies the line baud (for
     dialers and direct lines) or the port number (for network
     connections).

     The Class may be preceded by a non-numeric prefix.  This is
     to differentiate among devices that have identical Caller
     and baud, but are distinctly different.  For example,
     ``1200'' could refer to all Bell 212-compatible modems,
     ``V1200'' to Racal-Vadic modems, and ``C1200'' to CCITT
     modems, all at 1200 baud.	Similarly, ``W1200'' could denote
     long distance lines, while ``L1200'' could refer to local
     phone lines.

     Dialer applies only to ACU devices. This is the "brand" or
     type of the ACU or modem.

     DF02    DEC DF02 or DF03 modems.

     DF112   Dec DF112 modems. Use a Dialer field of DF112T to
	     use tone dialing, or DF112P for pulse dialing.

     att     AT&T 2224 2400 baud modem.

     cds224  Concord Data Systems 224 2400 baud modem.

     dn11    DEC DN11 Unibus dialer.

     hayes   Hayes Smartmodem 1200 and compatible autodialing
	     modems.  Use a Dialer field of hayestone to use tone
	     dialing, or hayespulse for pulse dialing.	It is
	     also permissible to include the letters `T' and `P'
	     in the phone number (in L.sys) to change to tone or
	     pulse midway through dialing.  (Note that a leading
	     `T' or `P' will be interpreted as a dialcode!)

     hayes2400
	     Hayes Smartmodem 2400 and compatible modems.  Use a
	     Dialer field of hayes2400tone to use tone dialing,
	     or hayes2400pulse for pulse dialing.

     novation
	     Novation ``Smart Cat'' autodialing modem.

     penril  Penril Corp ``Hayes compatible'' modems (they really
	     aren't or they would use the hayes entry.)

     rvmacs  Racal-Vadic 820 dialer with 831 adapter in a MACS
	     configuration.

     Expect/Send is an optional Expect/Send script for getting
     through a smart port selector, or for issuing special com-
     mands to the modem.  The syntax is identical to that of the
     Expect/Send script of L.sys.  The difference is that the L-
     devices script is used before the connection is made, while
     the L.sys script is used after.
