L-DEVICES(5) 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(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 contin‐ ued 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 follow‐ ing: 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_-_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 differ‐ entiate among devices that have identical _C_a_l_l_e_r and baud, but are dis‐ tinctly 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 let‐ ters ‘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 configura‐ tion. 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 configura‐ tion. _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 commands 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.
