I recommend all hardware and software mentioned above.
I like this idea.

However, most routers do not have USB ports, in which case the router has to be opened (https://wwwn.dd-wrt.com/wiki/index.p...alo_WHR-HP-G54) and wired to the serial transceiver (http://iguanaworks.net/product2.psp).

Do you think that will work equally well? Were you able to also record the OEM remote control signals on the router?

[EDIT] After more research, I've found that this will not work. The serial port interface ("SPI") internal to routers is not RS232, but rather 3.3v TTL. 3.3v is not enough to power any IR device on the market. A transceiver could be built for 3.3v TTL as a DiY project, but it probably would not have enough power to get across a room. In conclusion, daperl's approach needs a router that has a USB port.

(and no, it will not work to use a MAX3232 chip to convert a routers 3.3v TTL to RS232)
