 | | RCX transmitting on the IR over 2400

Dear friends, I am trying to use the lego RCX 2.0 over 2400 bps, actually at 4800 bps. I have no problems transmitting but Very rarely receives correctly. Any idea about this? Have you been in this road before? Thanks Rodrigo (17 years ago, 9-Aug-07, to lugnet.robotics)
