An October 1987 HewlettPackard Journal article on the infrared link
suggests that the LED frequency is 940 nm.  This article goes on to say
that the "infrared link uses 32.768 kHz as the infrared modulation
frequency".  The article goes into further details of the infrared
coding, etc. that I truthfully don't fully understand( I'm an aerospace
engineering undergrad, not an EE :-)  See if your library has a copy.
