Unresponsive after receiving spurious data

[Andy P. <an...@re...>]

I'm using a old packard bell serial port IR receiver with the lirc_serial
kernel module on ubuntu feisty, and the published tivo remote definition.

The problem I'm having is that occasionally (every few minutes) the IR
receiver "sees" false pulses (I cannot isolate the source), and after that it
oftentimes is un-responsive to genuine pulses from my remote.  The rest of the
time it works great, but this happens often enough to be frustrating.

I have strace-ed the lircd process, and I see it reading random numbers of
4-byte pkts of data when this happens.

Is there a way to make lircd time out and reset (it seems it could happen very
quickly) when it becomes clear that it's not going to receive a full set of
pulse data?  Am I missing some configuration option, or is my config file out
of date?

In case it might help, I've included my lircd.conf file below.

Thanks.
