FTDI Cable Transmitting Extra Gibberish Character

[dknguyen]

For some reason, my USB to RS-422 cable started sending an extra gibberish character for every character that I transmit. This gibberish character is unique and repeatable to the particular character that I myself sent. This does not happen when receiving. This was tested by looping the cable's own transmission lines back onto it's receive lines.

I am not aware of a setting (nor did I change any setting) that would cause a whole additional character to be sent with every transmitted character. Is anyone able to provide any clues?

It is a genuine FTDI device or one of the chinese clones?

Or, is there a possible problem with the driver - an auto update or corruption? I have seen problems on Windows systems with different driver versions.

Genuine. I didn't run an auto-update and at least I'm not aware of one occurring...
