Name
devices - Format of UUCP devices file.
Description
The Devices file (/usr/lib/uucp/Devices) contains
information for all the devices that can be used to
establish a link to a remote computer. These devices
include automatic call units, direct links, and network
connections. This file works closely with the Dialers,
Systems, and Dialcodes files.
Each entry in the Devices file has the following format:
type ttyline dialerline speed dialer-token
where:
type can contain one of two keywords (direct or
ACU), the name of a Local Area Network
switch, or a system name.
ttyline contains the device name of the line (port)
associated with the Devices entry. For
example, if the Automatic Dial Modem for a
particular entry is attached to the
/dev/tty11 line, the name entered in this
field is tty11.
dialerlineis useful only for 801 type dialers, which do
not contain a modem and must use an
additional line. If you do not have an 801
dialer, enter a hyphen (-) as a placeholder.
speed is the speed or speed range of the device.
It may contain an indicator for
distinguishing different dialer classes.
dialer-tokcontains pairs of dialers and tokens. Each
represents a dialer and an argument to be
passed to it. The dialer portion can be the
name of an automatic dial modem, or it may be
a direct for a direct link device.
For best results, dialer programs are preferred over Dialers
entries. The following entry is an example of an entry
using a dialer binary:
ACU ttynn - 300-2400 /usr/lib/uucp/dialHA24
Note all lines must have at least 5 fields. Use ``-'' for
unused fields. Types that appear in the 5th field must be
either built-in functions (801, Sytek, TCP, Unetserver, DK)

or standard functions whose name appears in the first field
in the Dialers file.
Two escape characters can be used in this file:
\D which means don't translate the phone /token
\T translate the phone /token using the Dialcodes
file
Both refer to the phone number field in the Systems file
(field 5). \D should always be used with entries in the
Dialers file, since the Dialers file can contain a T to
expand the number if necessary. \T should only be used with
built-in functions that require expansion.
Note that if a phone number is expected and a \D or \T is
not present a \T is used for a built-in, and \D is used for
an entry referencing the Dialers file.
Examples
The following are examples of common Devices files.
Standard modem line
ACU tty00 - 1200 801
ACU tty00 - 1200 penril
or
ACU tty00 - 1200 penril \D
A direct line
This example will allow cu -ltty00 to work. This entry
could also be used for certain modems in manual mode.
Direct tty00 - 4800 direct
A ventel modem on a develcon switch
``vent'' is the token given to the develcon to reach the
ventel modem.
ACU tty00 - 1200 develcon vent ventel
ACU tty00 - 1200 develcon vent ventel \D
To reach a system on the local develcon switch
Develcon tty00 - Any develcon \D
A direct connection to a system
systemx tty00 - Any direct

STREAMS Network Examples
A STREAMS network that conforms to the AT&T Transport
Interface with a direct connection to login service (i.e.,
without explicitly using the Network Listener Service dial
script):
networkx,eg devicex - - TLIS \D
The Systems file entry looks like:
systemx Any networkx - addressx in:--in: nuucp word: nuucp
You must replace systemx, networkx, addressx, and devicex
with system name, network name, network address and network
device, respectively. For example, entries for machine
``sffo'' on a STARLAN NETWORK might look like:
sffoo Any STARLAN - sffoo in:--in: nuucp word: nuucp
and:
STARLAN,eg starlan - - TLIS \D
To use a STREAMS network that conforms to the AT&T Transport
Interface and that uses the Network Listener Service dial
script to negotiate for a server:
networkx,eg devicex - - TLIS \D nls
To use a non-STREAMS network that conforms to the AT&T
Transport Interface and that uses the Network Listener
Service dial script to negotiate for a server:
networkx,eg devicex - - TLI \D nls

Notes
Blank lines and lines that begin with a <space>, <tab>, or
are ignored. protocols can be specified as a comma-subfield
of the device type either in the Devices file (where device
type is field 1) or in the Systems file (where it is field
3).
