L-DEVICES(5) UNIX Programmer's Manual L-DEVICES(5) NAME L-devices - UUCP device description file DESCRIPTION The L-devices file is consulted by the UUCP daemon _u_u_c_i_c_o(8) under the direction of _L._s_y_s(5) for information on the dev- ices that it may use. Each line describes exactly one dev- ice. 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 Printed 11/26/99 October 22, 1996 1 L-DEVICES(5) UNIX Programmer's Manual L-DEVICES(5) _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.) rvmacs Racal-Vadic 820 dialer with 831 adapter in a MACS configuration.

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.
