[Ftdi-usb-sio-devel] Multiple serial ports on one adapter

[Fred L. <ff...@ab...>]

All,

I need to have multiple RS422 ports on one computer and was looking at buying 
a USB/serial adapter with multiple (2) serial ports. My application is to 
plug two SICK laser scanners (lms200) into the computer.

I have essentially two questions.

The kernel driver help seems to say that it only supports single port adapters 
and I have seen at least one report on the archive of the mailing list saying 
that the driver didn't work with a multiple port adapter.  Is that indeed the 
case?

Second, is there a specific adapter that I should look at?  The one at 
<http://www.easysync.co.uk/index.html?lang=en-uk&target=d11.html> seems 
interesting.  Anybody has any experience with it?  The vendors explicitly say 
that it works with linux (related to the question above).

TIA,

Fred
