The length of the shortest IR receive message in bytes which will be considered a valid message and sent to the host.
IR receiver modules such as the one on the Slink-e tend to be very sensitive to both optical and electrical noise, causing them to occasionally generate false pulses when there was no actual IR signal. The false pulses are generally of short duration and do not contain the large number of on / off alternations present in a true IR remote signal. By setting a minimum message length, false pulses will be ignored and not reported to the host. bytes can range from 0 (no minimum) to 15 bytes (approx. 6 on-off transitions).
devname:irmml will set the IR minimum message length to 11 bytes
