Communications Port
Select the port (and interface if available) from the drop-down list, then click the ‘Next’ button. Note that in
addition to the serial ports, there is also an option to use the FDM (USB interface board). For some kernels
there are also other port options, such as USB Direct (eg. for the 2215UF), E8, E8Direct and FoUSB. For
Protocol A (legacy) kernels the ‘HMSE UPB’ interface is available in addition to Direct Connection.
