Jeroen,

It is a possibility that the serial cable may be a problem, or there may 
actually be a hardware issue with the machine itself.(Most of these 
machines are pretty old by computer world standards) :-) Sometimes just 
giving them a good cleaning with compressed air, and re-seating the RAM 
modules will make a difference. Just a thought... ;-)

P.S. I live in an area where dust is a major problem, and I have to blow 
the dust and crap out of mine about every 3 months or so. If I don't; 
when it *does* rain around here and the humidity goes up, I get all 
kinds of weird errors on some of my machines (the dust becomes 
electrically conductive). I experience this a lot with my customers 
machines too.
