OPTIONS

19       A summary of command line options is included below.  The X11 user
20       interface is described in the built-in manual.
21
22       -display display
23           Where to display the windows.  Default: $DISPLAY.
24
25       -geometry geometry
26           Specifies the size and position of the windows.  Default: 40x25.
27
28       -vbi device
29           Use the given device name.  Default: /dev/vbi0.
30
31       -finetune -4..4|auto
32           Try some fine tuning if you have a lot of decoding errors (these
33           lightning symbols).  This allows fine tuning of the decoder cir‐
34           cuit.  The pre finetune behaviour was -finetune 0.  Default: 1.
35
36       [-parent] ppp[.ss]
37           Open a new window with the page number given by ppp and an optional
38           subpage index given by ss.
39
40           The -parent keyword is just for completeness and not normally used.
41           The page number alone is sufficient.  Default: 900.
42
43       -child ppp[.ss]
44           Open a new child window with the page number given by ppp and an
45           optional subpage index given by ss.  About the concept of parent
46           and child windows see the built-in manual.
47
48       -erc/-noerc
49           Enables/disables the error reduction code which substitutes errors
50           on a page by data from a previously received one.  Enabled by
51           default.
52
53       -bell/-nobell
54           Enables/disables the error bell.  Normally enabled.
55
56       -charset latin-1|latin-2|russian|iso8859-7
57           Selects the character set to use.  Characters not present in the
58           selected set are replaced by similar looking symbols.  (default:
59           latin-1)
60
61       -doublefont/-df
62           Instructs alevt to use double sized fonts.
63
64       --help
65           Show summary of options.
66
67       --version
68           Show version of program.
69
70       The order of options is important!  Each page number opens a new window
71       with the previously given geometry, device, and display.  For example,
72       to open two windows on the local display and one on display foo:0 you
73       would start it with:
74
75              alevt 100 300 -display foo:0 100
76
77       Or, one window from /dev/vbi0 and one from /dev/vbi1 (untested *g*):
78
79              alevt -vbi /dev/vbi0 100 -vbi /dev/vbi1 100
80
81       The -child options requires a parent window.  So, it must be preceded
82       by a parent or another child window.
83
84       When saving pages alevt asks for a format string.  Look at alevt-
85       cap(1).  The chapter Format Specifiers gives an explanation.
86
87       alevt has no support to set or change the TV channel.  This should be
88       done with another (not supplied) program like xawtv or set-tv from the
89       xawtv package.  Maybe in the future there will be a more sophisticated
90       method in bttv to switch channels etc with a dedicated tuner applica‐
91       tion.  But, at the moment, you have to live with it...
