[Elecraft] KXUSB

[Paul Jewell]

Hi Don,

I should have given more details -

  * Running linux
  * ftdi drivers are all installed, and the port of /dev/ttyUSB0 is
    installed
  * The Tx lights are flashing on the ftdi adaptor, suggesting it is
    working as expected. I may plug another device in to see if I can
    confirm this (perhaps a null modem of some sort)
  * I did try to swap the RXD and TXD, but this was on a different ftdi
    adaptor - I will try again with this current ftdi device. I will
    also try a different PC when I go in the house (this will give me a
    chance to try Windows instead as well).

Thanks for the comments!

73,
