Ok, I recently built a null modem cable to network my Windows 98 and XP computers together. (Serial, not parallel) But, they are on opposite ends of the house. (The two computers.) So my cable runs through the house, one, being and eye-sore, and two, being very easy to trip on. So, I can't keep in there all the time. So I need to build an IR communication. I need it to be reliable, capable of 115200 bp, and to be able to transmit at least 50 feet or so. Can anyone help me please? Thanks.
