I am working on a point of sale project where one of the requirements is to allow the locations to use their legacy dumb character terminals and serial printers. I'm looking for recommendations for a 16-port device to use, with my priorities being 1) ease of setup/configuration and 2) price. Any suggestions?

Thanks in advance,
Mike

I've never need that many serial ports so can't recommend anything.
There are several manufactures that state linux supported
