L-DEVICES(5)                                                      L-DEVICES(5)


NAME
       L-devices - UUCP device description file

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

       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  contin‐
       ued by appending a ‘\’ character to the end of the line.

       Caller  denotes  the type of connection, and must be one of the follow‐
       ing:

       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 connections in L-devices is
               superfluous; uucico does not even bother to look here since  it
               has all the information 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 differ‐
       entiate among devices that have identical Caller and baud, but are dis‐
       tinctly  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 let‐
               ters ‘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 configura‐
               tion.

       va212   Racal-Vadic 212 autodialing modem.

       va811s  Racal-Vadic 811s dialer with 831 adapter.

       va820   Racal-Vadic 820 dialer with 831 adapter.

       vadic   Racal-Vadic 3450 and 3451 series autodialing modems.

       ventel  Ventel 212+ autodialing modem.

       vmacs   Racal-Vadic 811 dialer with 831 adapter in  a  MACS  configura‐
               tion.

       Expect/Send  is  an  optional  Expect/Send script for getting through a
       smart port selector, or for issuing special commands 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.
