I'm not familiar with your receivers but I am assuming that they use  
different codes, so one remote doesn't interfere with the other.

The MyBlaster device actually knows the various codes itself, rather  
than depend on lirc to tell it what they are.

So you simply send a serial message to the MyBlaster telling it what  
code set and what command to send, the codeset selection is part of  
the perl script that sends the commands.

So you simply have two different perl scripts, one for each device,  
but they both talk to the same MyBlaster and thus need only one  
serial port.

If you are using two identical devices and depending on some sort of  
light isolation to keep them from responding to each other then this  
method will not work.
