I want to setup a 'data logger' for rain water tanks and hot water storage
tanks, for this I'll need at leats 3 RS232 ports
luckily, the vinatge of computers found at rubish tips, oops, recycling
places, generally has two RS232 ports, but, that still leaves me short of
one port:
I have several multi RS232s cards, but, ISA, which is of not much use
should I get a PCI multi RS232 card,
or, go for USB-with-two-RS232 ports gadget ?
(or, get another PC, and use two PCs...)
