[Gambas-user] serial port issue

[Ron]

I have no experience with the cable in my link, I just found it 
yesterday, but make sure your usb to serial converters have a FTDI chip 
inside.
Not (like most of mine) an Prolific PL2303 chip since they all have the 
same device id and serial number, so you have a small problem identifing 
them.

I have not installed any drivers, but I had to lock them like this:

Here is an old photo of my test server showing some of them:

Using Ubuntu 9.10

Ron.
