Serial Port to USB Adapter and Mac OS X

[Christopher Hunt]

Hi there,

I'm looking to communicate with two rear projectors via a published  
serial port protocol. Can anyone recommend a tried serial port to usb  
cable/adapter that works well with the termios api?

I've found a number of adapters including the Belkin one:

...but I've been unable to find out whether they're programmed via  
termios.

Additionally if I plug in two of these types of adapter, then should  
I be able to address them as individual serial ports?

Kind regards,
Christopher
