9 | .SH NAME | |
10 | L-devices \- UUCP device description file | |
11 | .SH DESCRIPTION | |
12 | The L-devices file is consulted by the UUCP daemon | |
13 | .IR uucico (8C) | |
14 | under the direction of | |
15 | .IR L.sys (5) | |
16 | for information on the devices that it may use. | |
17 | Each line describes exactly one device. | |
18 | .PP | |
19 | A line in | |
20 | .I L-devices | |
21 | has the form: | |
22 | .PP | |
23 | Caller Device Call_Unit Class Dialer [Expect Send].... | |
24 | .PP | |
25 | Each item can be separated by any number of blanks or tabs. Lines beginning | |
26 | with a `#' character are comments; long lines can be continued by appending | |
27 | a `\e' character to the end of the line. | |
28 | .PP | |
29 | .I Caller | |
30 | denotes the type of connection, and must be one of the following: | |
31 | .TP 8 | |
32 | .B ACU | |
33 | Automatic call unit, e.g., autodialing modems such as the Hayes | |
34 | Smartmodem 1200 or Novation ``Smart Cat''. | |
35 | .TP 8 | |
36 | .B DIR | |
37 | Direct connect; hardwired line (usually RS-232) to a remote system. | |
38 | .TP 8 | |
39 | .B DK | |
40 | AT&T Datakit. | |
41 | .TP 8 | |
42 | .B MICOM | |
43 | Micom Terminal switch. | |
44 | .TP 8 | |
45 | .B PAD | |
46 | X.25 PAD connection. | |
47 | .TP 8 | |
48 | .B PCP | |
49 | GTE Telenet PC Pursuit. | |
50 | .TP 8 | |
51 | .B SYTEK | |
52 | Sytek high-speed dedicated modem port connection. | |
53 | .TP 8 | |
54 | .B TCP | |
55 | Berkeley TCP/IP or 3Com UNET connection. These are mutually exclusive. | |
56 | Note that listing TCP connections in | |
57 | .I L-devices | |
58 | is superfluous; | |
59 | .I uucico | |
60 | does not even bother to look here since it has all the information it | |
61 | needs in | |
62 | .IR L.sys (5). | |
63 | .PP | |
64 | .I Device | |
65 | is a device file in /dev/ that is opened to use the device. The device | |
66 | file must be owned by UUCP, with access modes of 0600 or better. (See | |
67 | .IR chmod (2)). | |
68 | .PP | |
69 | .I Call_Unit | |
70 | is an optional second device file name. | |
71 | True automatic call units use a separate device file for data and for dialing; | |
72 | the | |
73 | .I Device | |
74 | field specifies the data port, while the | |
75 | .I Call_unit | |
76 | field specifies the dialing port. | |
77 | If the | |
78 | .I Call_unit | |
79 | field is unused, it must not be left empty. | |
80 | Insert a dummy entry as a placeholder, such as ``0'' or ``unused.'' | |
81 | .PP | |
82 | .I Class | |
83 | is an integer number that | |
84 | specifies the line baud (for dialers and direct lines) or the port number (for | |
85 | network connections). | |
86 | .PP | |
87 | The | |
88 | .I Class | |
89 | may be preceded by a non-numeric prefix. | |
90 | This is to differentiate among devices that have identical | |
91 | .I Caller | |
92 | and baud, but are distinctly different. | |
93 | For example, ``1200'' could refer to all Bell 212-compatible modems, | |
94 | ``V1200'' to Racal-Vadic modems, and ``C1200'' to CCITT modems, | |
95 | all at 1200 baud. | |
96 | Similarly, ``W1200'' could denote long distance lines, while ``L1200'' | |
97 | could refer to local phone lines. | |
98 | .PP | |
99 | .I Dialer | |
100 | applies only to ACU devices. This is the "brand" or type of the ACU or modem. | |
101 | .TP 8 | |
102 | .B DF02 | |
103 | DEC DF02 or DF03 modems. | |
104 | .TP 8 | |
105 | .B DF112 | |
106 | Dec DF112 modems. Use a | |
107 | .I Dialer | |
108 | field of | |
109 | .B DF112T | |
110 | to use tone dialing, or | |
111 | .B DF112P | |
112 | for pulse dialing. | |
113 | .TP 8 | |
114 | .B att | |
115 | AT&T 2224 2400 baud modem. | |
116 | .TP 8 | |
117 | .B cds224 | |
118 | Concord Data Systems 224 2400 baud modem. | |
119 | .TP 8 | |
120 | .B dn11 | |
121 | DEC DN11 Unibus dialer. | |
122 | .TP 8 | |
123 | .B hayes | |
124 | Hayes Smartmodem 1200 and compatible autodialing modems. | |
125 | Use a | |
126 | .I Dialer | |
127 | field of | |
128 | .B hayestone | |
129 | to use tone dialing, or | |
130 | .B hayespulse | |
131 | for pulse dialing. | |
132 | It is also permissible to include the letters `T' and `P' in the phone | |
133 | number (in | |
134 | .IR L.sys ) | |
135 | to change to tone or pulse midway through dialing. | |
136 | (Note that a leading `T' or `P' will be interpreted as a dialcode!) | |
137 | .TP 8 | |
138 | .B hayes2400 | |
139 | Hayes Smartmodem 2400 and compatible modems. | |
140 | Use a | |
141 | .I Dialer | |
142 | field of | |
143 | .B hayes2400tone | |
144 | to use tone dialing, or | |
145 | .B hayes2400pulse | |
146 | for pulse dialing. | |
147 | .TP 8 | |
148 | .B novation | |
149 | Novation ``Smart Cat'' autodialing modem. | |
150 | .TP 8 | |
151 | .B penril | |
152 | Penril Corp ``Hayes compatible'' modems (they really aren't or | |
153 | they would use the | |
154 | .B hayes | |
155 | entry.) | |
156 | .TP 8 | |

177 | .PP | |
178 | .I Expect/Send | |
179 | is an optional | |
180 | .I Expect/Send | |
181 | script for getting through a smart port selector, | |
182 | or for issuing special commands to the modem. | |
183 | The syntax is identical to that of the Expect/Send script of | |
184 | .IR L.sys . | |
185 | The difference is that the | |
186 | .I L-devices | |
187 | script is used | |
188 | .I before | |
189 | the connection is made, while the | |
190 | .I L.sys | |
191 | script is used | |
192 | .IR after . | |
