L-devices - UUCP device description file
DDEESSCCRRIIPPTTIIOONN
The L-devices file is consulted by the UUCP daemon
_u_u_c_i_c_o(8C) under the direction of _L_._s_y_s(5) for information
on the devices that it may use. Each line describes
exactly one device.
A line in _L_-_d_e_v_i_c_e_s 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.
_C_a_l_l_e_r denotes the type of connection, and must be one of
the following:
AACCUU Automatic call unit, e.g., autodialing modems such
as the Hayes Smartmodem 1200 or Novation ``Smart
Cat''.
DDIIRR Direct connect; hardwired line (usually RS-232) to
a remote system.
DDKK AT&T Datakit.
MMIICCOOMM Micom Terminal switch.
PPAADD X.25 PAD connection.
PPCCPP GTE Telenet PC Pursuit.
SSYYTTEEKK Sytek high-speed dedicated modem port connection.
TTCCPP Berkeley TCP/IP or 3Com UNET connection. These are
mutually exclusive. Note that listing TCP connec-
tions in _L_-_d_e_v_i_c_e_s is superfluous; _u_u_c_i_c_o does not
even bother to look here since it has all the
information it needs in _L_._s_y_s(5).
_D_e_v_i_c_e 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 _c_h_m_o_d(2)).
_C_a_l_l___U_n_i_t is an optional second device file name. True
automatic call units use a separate device file for data

and for dialing; the _D_e_v_i_c_e field specifies the data port,
while the _C_a_l_l___u_n_i_t field specifies the dialing port. If
the _C_a_l_l___u_n_i_t field is unused, it must not be left empty.
Insert a dummy entry as a placeholder, such as ``0'' or
``unused.''
_C_l_a_s_s is an integer number that specifies the line baud
(for dialers and direct lines) or the port number (for
network connections).
The _C_l_a_s_s may be preceded by a non-numeric prefix. This
is to differentiate among devices that have identical
_C_a_l_l_e_r and baud, but are distinctly different. For exam-
ple, ``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.
_D_i_a_l_e_r applies only to ACU devices. This is the "brand" or
type of the ACU or modem.
DDFF0022 DEC DF02 or DF03 modems.
DDFF111122 Dec DF112 modems. Use a _D_i_a_l_e_r field of DDFF111122TT to
use tone dialing, or DDFF111122PP for pulse dialing.
aatttt AT&T 2224 2400 baud modem.
ccddss222244 Concord Data Systems 224 2400 baud modem.
ddnn1111 DEC DN11 Unibus dialer.
hhaayyeess Hayes Smartmodem 1200 and compatible autodialing
modems. Use a _D_i_a_l_e_r field of hhaayyeessttoonnee to use
tone dialing, or hhaayyeessppuullssee for pulse dialing. It
is also permissible to include the letters `T' and
`P' in the phone number (in _L_._s_y_s) to change to
tone or pulse midway through dialing. (Note that
a leading `T' or `P' will be interpreted as a
dialcode!)

_E_x_p_e_c_t_/_S_e_n_d is an optional _E_x_p_e_c_t_/_S_e_n_d 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_._s_y_s. The difference is that
the _L_-_d_e_v_i_c_e_s script is used _b_e_f_o_r_e the connection is
made, while the _L_._s_y_s script is used _a_f_t_e_r.
