Infrared Ports for file transfers

["w.t.brown" <wtbrown@gte.net>]

I have a Thinkpad 560, pentium 120mz, 24 mb ram. I normally use a serial
cable to copy files back and forth to my desktop, at a speed of 115kps.  I
was thinking of buying a jeteye for my desktop to use with 
the infrared port on my 560 to copy files.  However, Mobile Computing
magazine said their test of infrared
ports showed they effectively only operate at the very slow speed of about
75kps, way too slow.

Has anyone any experience with using infrared ports to copy large files to
a desktop?
