The perl module that you want is "Time::HiRes". You didn't mention  
what distro you are using but there is a very good chance that it is  
already installed, it was on my MythDora system.

Since you were trying to get an LIRC-based blaster working you will  
have to un-do some of your steps along that line as it may be  
hijacking your serial port. If you added anything to rc.local or  
modprobe.conf take it back out.

How did you try and install the perl module ?? The best way to do  
that is through cpan. Your attempt to use the link failed because the  
version has been updated (I hate it when people put version numbers  
in links, they will almost certainly change). Try the link at the  
bottom of the page but truncate the URL after "~jhi/" You will find  
the current version is 1.87. ie:

http://search.cpan.org/~jhi/Time-HiRes-1.87/

But why not just try it first ? I didn't use the CodeSearch script, I  
just used the MyBlaster.pl and tried all of the appropriate codes,  
which can be found in the docs, you will need the device type  
(probably "3" for sat rcvr) and the device code, there are about 10  
for Dish receivers, the one you want will depend on what ID your  
remote is using. You will also have to make sure the correct serial  
port line is un-commented.

You may call it a piece of junk if you wish, but it is working  
perfectly for me after less than 10 minutes of effort.

The unit from irblaster will work as well, it just takes a bit more  
effort. Think of it as "sweat equity" in your system because you do  
save money.

So:

Re-boot, as the system comes up check your BIOS settings on the  
serial port.

Install the scripts someplace. Edit them for serial port and device  
type.

Try "MyBlaster.pl power", see if your receiver turns off (takes a  
second or two)

If it doesn't, try another code.

That's all I did, it was the tenth code I tried.
