2 | * sa_control - control for Scientific Atlanta Cable Boxes, including |
---|
3 | * the 4250 HDC which is unsupported in sa3250ch.c |
---|
4 | * Based on sa3250ch.c, firewiredevice.{h.cpp}, and linuxavcinfo.{h,cpp} |
---|
5 | * |
---|
6 | * Martin Purschke ( mpurschke (at) gmail.com ) 11/28/2009 |
---|
7 | * |
---|
8 | * allows to change the channel, query the power status, and turn |
---|
9 | * the power on and off |
---|
10 | * |
---|
11 | * Usage: sa_control [-v] [-q] [ channel | on | off ] |
---|
12 | * -h : this help |
---|
13 | * -v : verbose, multiple -v for more verbosity |
---|
14 | * -q : query power status, also sets exit status |
---|
15 | * <channel> : set channel, implies power on |
---|
16 | * -w <ms> : after a channel change, wait so many |
---|
17 | * more milliseconds to allow the box time to tune |
---|
18 | * on : switch on |
---|
19 | * off : switch off |
---|
20 | * Examples: |
---|
21 | * sa_control -q |
---|
22 | * sa_control -q -v |
---|
23 | * sa_control -q -v -v |
---|
24 | * sa_control 702 |
---|
25 | * sa_control -w 6000 702 |
---|
26 | * sa_control off |
---|
27 | * |
---|
28 | * Build it with |
---|
29 | * g++ -o sa_control sa_control.cc -lrom1394 -lavc1394 -lraw1394 |
