Hello everyone:

I know, I know, the IR-blaster topic has appeared a few times and I did search and found the very good instructions at

http://losdos.dyndns.org:8080/public/mythtv-info/MythTV_DISH_IR_LED_TX_via_Modified_LIRC.html

But after following such instructions, unfortunately, ledxmit does not seem to be loading. In the instructions, right before starting the section for STAGE 3, there are three lines that should appear in dmesg, they look like this:

in my case, I am getting the following relevant lines out of dmesg:


These are my conditions:
AMD Athlon
Working KnoppMyth R5V30
Hauppage 250 with remote control and working fine to control MythTV.

On following the instructions the first time around, I couldn't pass either the disabling of the serial driver or the installation of the new one. So, instead of using LIRC 0.7.2, I went ahead and downloaded the latest one (LIRC 0.8)...got pass that.

By the way, since my machine only has one COM port on the back, I am trying to use COM1 (ttyS0). Then again, in dmesg output there are a couple of lines about ttyS1...what is that about?.

Does anybody have any idea what might be happening?
Do the various lines from dmesg tell anything?

Any help will be greatly appreciated...I am SOOO close!!!!

kinda strange that kernel finds S0 at 03f8 and ledxmit_serial finds S0 at 02f8.

try configuring it for S1..

how is the serial port configured in the bios?

First of all, thanks for the quick reply.

I will try what you suggest...I just don't know what to do first...maybe what's easier?

I guess I should try configuring for S1, first.

Trying to see the bios is going to be a little difficult from the point (of ignorance) that I stand. Presently I have TV-out only, no monitor at the computer and work remotely via an x-server/client (cygwin on my laptop). O.k., maybe is not difficult, all I need to do is take the TV-out out of the whatever file is in and bring a monitor in...unless there is a trick to see the bios after booting? You know, from an xterm?

I will post again with results.

I think I found your problem.



So...try putting the setserial /dev/ttyS0 uart none command where it belongs. You may have missed a step from that wiki page.

Well, not working yet. Here is what I have done.

First, I found an entry in /etc/X11/XF86Config-4 that has something to do with a serial mouse, so I commented that out, just in case.

Made no difference.

Then, I went ahead and configured the IR-blaster to use COM2. Configuration passed the tests indicated in the instructions and the lines from dmesg turned out like this:



Yet, nothing works, anyway.

Then, I realized that at boot time, the resolution on my TV is pretty decent and I don't need to bring a monitor to the PC, I can just use the TV itself...so, I went ahead and took a look at the BIOS, I found this:



So, in effect, the one serial port in my machine is in 3F8, yet, as you can see, the lines from the original dmesg indicate that ledxmit is trying to get com1 at 2f8!

And just answer to afrosheen, let me say that I have added



at the bottom of /etc/init.d/bootmisc.sh, as indicated in the instructions.

One thing just ocurred to me...I am going to go back and modify the original myth-ledxmit.sh and specify com1 right there...maybe that thing about configuring com2 as default and later on actually requesting com1 is not cutting it for me.

Other than that, anymore ideas?

O.k....it's working.

Like I said, I went back to the instructions at

http://losdos.dyndns.org:8080/public/my ... _LIRC.html

but instead of using the the script myth-ledxmit.sh "as-is", I modified it to use COM1 right from the start.

What happened is that the instructions lead me to believe that using the script myth-ledxmit.sh "as-is" is o.k., even though it sets up COM2 as the default port for the IR-blaster; and that later on, one can choose COM1 by explicitely requesting in bootmisc.sh...Well, that did not quite work for me.

There you have it and thanks everybody for their pointers.
