By my understanding from a serial port howto I found online, Linux automatically tries to configure the first four serial ports, but I could be mistaken. <BR><BR>The issue is that I am unable to locate the base address and IRQ in use for the serial ports to properly configure lirc, and using the defaults results in an irexec error.<BR><BR><BR>As far as the IR port on the PVR-150, I am already using that for my remote control input, so I'm stuck there. <BR></BLOCKQUOTE><BR></DIV></SPAN></DIV><DIV style="direction: ltr;"><DIV>The newer PVR-150s come with an IR receiver and an IR blaster, I think the reference above was to using the "blaster" not the receiver.

In the case of satellite receivers you can set the receiver to use one of several code sets to prevent interference if you have more than one receiver, thus you can use a single IR transmitter to control several receivers. </DIV><DIV><BR></DIV><DIV>Have you checked to see if your cable boxes have this capability?

If it turns out you can do this it will make oyur life much simpler because even if you work out using multiple serial ports you will still have to isolate the boxes from each other optically.</DIV></BODY></HTML>
