NAME
L-devices - UUCP device description file
DESCRIPTION
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:
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-_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 infor-
mation 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 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.
_D_i_a_l_e_r 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 _D_i_a_l_e_r 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 _D_i_a_l_e_r 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._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!)
hayes2400
Hayes Smartmodem 2400 and compatible modems. Use a
_D_i_a_l_e_r 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.)

_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.
