From: Jaimie Vandenbergh on 11 Feb 2010 14:23 I've just got back into scuba diving (thanks to a short holiday bobbing up and down in the red sea), and need to get my dive computer connected to slurp out my dives. It's a Suunto Vyper, and it's got an old 9 pin D shell serial connector. Nasty. I can buy a proper USB lead from the manufacturer, for a mere 65quids (which includes the software that I already have). Or I can buy a 3rd party USB cable for it which appears to be a builtin USB-serial converter, but that needs a driver - and they haven't got a Snow Leopard one yet. And it's 25 quid, anyway. http://www.customidea.com/shop/product_info.php?products_id=99 USB to serial adapters get a bad rep, rightly so, due to using 5V where serial should be 7-12V or some such. Anyone know any good ones that work in Snow Leopard? Cheers - Jaimie -- A mind stretched by an idea can never go back to its original dimensions. - Conan Doyle

No idea about drivers, etc. Just another option. Prices vary a lot and seem to overlap the range you mention. -- Rod

Unfortunately not - Minis, MBP13" and Air here, nothing other than USB or firewire to use. Unless some loony has made an ethernet-serial adapter.

I thought most decent ones used DC-DC converters, charge pumps and specialised driver chips to at least provide +-5V (which puts them within spec). From my experience 'problems' were often down to how the other signals (RTS, CTS, CD, DSR etc) were handled. Luckily, all my real computers have real serial ports (including the ASROCK ATOM 330 A330GC S/V/L MINI-ITX board I've just bought. You never know when they might come in handy eh!) ;-) T i m

You'd think it'd be cheaper to just provide USB nowadays. > I can buy a proper USB lead from the manufacturer, for a mere 65quids > (which includes the software that I already have).
