Anyone any experiences with USB to serial adaptors - and good/bad suggestions? I've hear the Belkin one possibly works OK. I have a java ignition controller project that has to communicate via RS232, and haven't any system with a serial port. Also, anyone have one of these lying around redundant that they'd like a few beer tokens for?

All of the USB-Serial adapters I have encountered seem to have latency issues, in the past I have supported some engineers with laptops who used serial interfaces to some production line equipment and the only thing I could get to work reliably for them was the Brainbox PCMCIA Serial port card.

AFAIK Brainboxes repleased GPL drivers for most of their cards a while ago, check first but getting the card to work in Linux should be easy. But be warned that these cards are not cheap.
if you are dealing with a desktop then you may well find the serial ports on the systemboard, have not been brought out to the back panel.

I ended up paying about £70 for my brainboxes PCMCIA card. It worked flawlessly with the kernel drivers (~around the time of RedHat 9). The PCMCIA card worked with absloutely no problems.

I bought one from www.Ebuyer.com a couple of years ago and it has worked fine on my laptop ever since. Works out of the box with gtk-term and you can even toggle the handshake lines. They are only a few pounds; their product code is: 40608

D-Link DU-H4SMK, circa 1999, 4-port USB hub with RS-232, PS/2 mouse port and PS/2 keyboard port. Going spare in Wymondham for next to nowt. Windows driver disc missing but never could get the bugger to work properly anyway.
