Greetings, Thanks so much for your reply Kit. /dev/udp is not an actual device that you will see in /dev. It is a bash call to open a udp port to read or write to/from. You can also do this in bash with tcp. For example Some Data > /dev/udp/<IP address>/<port> Some Data > /dev/tcp/<IP address> I used it like $printf "data" > /dev/udp/ip/port Cheers Tim Camp WZEW-FM On Fri, Oct 23, 2020, 2:21 PM Kit Haskins <k...@ka0wuc.org> wrote: > I don't have a /dev/udp in either my Ubuntu (20.04) nor Centos 6.8 (old > box) > > While what I'm going to suggest fixed another problem with permissions, > I'll toss it out here, knowing there are many smarter people reading this > thread: > > I had issues with access to the serial ports /dev/ttyUSBx ...
