I created an RS422 RJ45 loopback cable by connecting pin 1 to pin 8 and pin 4 to pin 5.
I also connected a few of the other pins that aren't used since it made it easier to line everything up into an RJ45 plug.
However, when I type a letter, it appears twice. For instance, if I type ABC, this shows up:
AABBCC
At first, I thought local echo was enabled. However, I checked, and it's disabled.
Any ideas why I'm seeing double?
