I have an older Home-Electronics IRA infrared serial port receiver. The IRA has a green/red light indicating connection to the serial port. In the past, I've had this configured in Windows XP/Vista, so I know the receiver, cable, serial port all work on this computer. On the Ubuntu/Mint side, i've installed lirc and experimented with different serial settings, either through dpkg-reconfigure lirc or by manually entering the /etc/lirc/hardware.conf. From internet posts, the key hardware.conf parameters are: REMOTE_MODULES="lirc_dev lirc_serial", REMOTE_DRIVER is irman, default or blank; REMOTE_DEVICE is /dev/ttyS0 or /dev/lirc0. I restart lirc and see that lirc is running: /usr/sbin/lircd --driver=irman --device=/dev/ttyS0. Also installed libirman-dev.
I've tried everything i can find/think of to make this work. I'm beginning to think that the serial hardware device doesn't work with linux (i hope / doubt that). It works with Vista, so it should work with Linux:) What is odd is that the device does not appear to be connected to the serial port. The red/green light is not on. When running irw, there is no response. Again, this tells me that the IR receiver is not connected. (It is connected, i dual boot back to Vista and it works fine).
I've seen posts about setserial none (tried that, didn' work) and claims to revert to old versions of lirc (haven't tried that as I want to keep Mint like new). Is there anything I need to do to make this connect to the serial port?
