With a 'mutex'd wrapper script that does channel Sky sleep channelagainifnotcalledsince (allows repeated cslls to change channel without interferences, and copes with having to possibly turn the box on) it's all working a dream.

post your wrapper and i'll give it a whirl
also, post your changes to use nanosleep()
Here goes; cat'd over SSH and reformatted in case there's anything
odd in there :-)
Not sure the locking functions (purloined) are really as tidy as I'd
want [hence the possibility of rolling it all into one perl script using
flock()] but it seems to suffice, and be nice reliable, so for the
time being, it stays.

Re: [mythtv-users] UK - Controlling Sky boxes
I'm using a sir dongle which plugs into the ir header on my motherboard with no problems. The particular one I'm using is an asus, but I have another which also works. I've seen adaptors available on the net for most MBs. I'm using lirc 0.7pre, I learnt the codes from my sky remote, as all the ones I found on the net did not work. I'm also calling the channel.pl file directly from myth rather than the wrapper shell script. If you are having a problem, try using lirc (irrecord) to learn your particular remote. The header is atached to the PC via a lead salvaged from a scrap ps/2 mouse, and I'm using a ps/2 port on a slot plate again liberated from a scrap PC. Granted, it does not look nice, but it works. BTW I'm thinking about moving my backend out of the living room. My sky box is connected presently via svideo. If I set the frequency ID on each sky channel to the uhf channel on the tuner, and change the input to the tuner, does anybody know if it will use the channel ID to send the commands to change, and select the correct rf channel on the tuner? -- No virus found in this outgoing message.

[mythtv-users] UK - Controlling Sky boxes
Hey Guys Have been looking at this: http://www.cornelius.demon.co.uk/lirc-sky-rflink-howto.html Which effectively shows how to control a Sky (or Sky+) Digibox from the serial port.. I've looked at the link for the RFLink thats mentioned and given them a call to ask if they can provide one that already has a serial port on the end (the one they make is for Tivo's) but they don't. I know I could modify one myself but I don't really have the time or patience to be cutting things up and soldering them back together - so I was wondering if anyone knows of a UK supplier that makes this type of item ready-made.. I'd prefer to use this method rather than a IR approach as this seems a bit tidier and means I don't have to go taping bits to the IR reciever on the front of the Sky box.. Up till this point (have been running a Myth box for over a year now) I've been setting schedules up in myth and then setting the Sky box to autoview/series link .. but this isn't perfect.. and effectively makes MythWeb pointless.. am wanting to be able to set recordings remotely... and unless the Sky box happens to already be on the channel I want to record on.. I can't do this.. Any ideas/links would be appreciated Craig ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] UK - Controlling Sky boxes
Hi Craig I've not played with this myself, but would love to hear how you get on with it if you try. I use the RF extender on the Sky box so that I can control it from another room, so that works well. For changing the channels, I use an IR transmitter from Red Remote - http://www.redremote.co.uk/serial/ I'm absolutely delighted with it, and it works very well indeed. The only problem I found was that I needed to use a Windoze machine to program it for the Sky box. That wasn't a great hassle though. If you're interested, the script I wrote for changing channels is quite simply: #!/bin/sh /usr/share/mythtv/red_eye /dev/ttyS0 TK$1 2 /usr/share/mythtv/red_eye /dev/ttyS0 KK 5 Anyway, I look forward to hearing how you get on.
