We have a project in a gas stations group. In each gas station we will be connecting several serial peripheral in the V10L, using converter of USB for serial.
There is a specific USB to serial converter from wyse with the driver built in and these will work. Also I have use the Targus USB to serial cable and this worked as well. If you do have V10L make sure you update the BIOS from 1.04 to 1.10 as it fixes a COM port IRQ issue – the update is on the Wyse V10L download page,
