It very likely won't.

But this will :-

Amazon seem to ship two different version of the lead, one uses the Prolific drivers and the other uses an installer package called 'CH341SER.exe', this is sometimes supplied on disk with the lead but more often that not you need to google 'CH341SER.exe' and download it from the manufactures web page 'http://www.wch.cn/download/.....', Once the driver is installed the the lead works fine.

AFAIK the very cheap adapters are designed to work primarily with olde worlde modems and terminals .... but not with every type of RS232-equipped device. Some applications need to communicate with a real hardware UART (16550 usually ISTR)

Remember the introduction of AC97 audio and modems on PC motherboards ? These used the main CPU (and/or bits of the south brdige ?) to emulate some of the reqd. functionality .....
Well AFAIK its similar with the very cheap USB->RS232 adapters, and if the app is written to address a real serial port it just doesn't work with an emulated (or partly emulated) port.

The Keyspan branded ones I mentioned have a real hardware UART - hence the relative cost.

Was nice knowing you, SH.

Got a Dell PIII-M 1.2GHz laptop here ... 12" XGA screen, 1GB RAM, 20GB disk, solid build quality, reliable ....... and has a proper serial port. Up for grabs for slightly more than the price of the keyspan adapter I linked to. (am I allowed to say that ?) .... If it gets nicked/smashed/beer spillage .... well you'd likely just suck your teeth a bit .... what if that happens to your dual-core 4GB jobby ?

+2

Good advice, got myself a £100 Dell laptop from ebay which is dedicated to rig use, no qualms about leaving it hooked up unattended.

Having said that if you just want to mess around at home I can confirm these work:

USB is not a useful interface for audio processors, limited length, under windows tends to appear on random ports, and TBH if you don't know how to plumb into an RS-232/485 line you probably shouldn't be accessing the kit anyways.
