IRMan Receiver

The IRMan receiver is a nifty little IR receiver that can be purchased here.

The big difference between this device and the one before is that this device has a microcontroller that allows it to talk over the normal receive and transmit lines for a serial port. The other one was a very simple circuit using non-standard lines. The software side of the other device is much more complex, requiring lower level access to the serial port and requiringthe software to decode the signals coming from the non-standard lines. That is why we use lirc to read from the first device, but we can use any terminal program such as minicom to read from this one. The beauty of open source is that if you really want to know how to do the low level stuff, start digging through the source code for lirc. The details are all right there in the code.
