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 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 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 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.
- 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 configuration.
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.
