minicom has me typing every character twice, which is extremely tiring. That is I have to press 'aa' to get 'a' and so on.

Does anyone know which setting is wrong, or what I should do?

I have Beaglebone Black with a custom Linux kernel 3.12.24 on a minimal rootfile-system, connected with the UBS-serial adapter, and hooked up to Ubuntu 14.04.

    Describe your setup. What is on the other end of the serial link?

  • I have a BeagleBoneBlack with a adafruit.com/products/954 USB-to-serial adapter. Then I enter "minicom" and it works, but I have to double-tap each key...

    Your description is still vague. Edit your original question with the hardware and software used at both ends of the serial link. When you type a key in a terminal emulator program, the displayed (or not displayed) character is generated either locally (not commom) or (remotely) by the program on the other end of the serial link (most common configuration). So the issue could be either the transmission and/or the reception at either the near or far end of the serial link or both ends.

I had the same problem once trying to communicate with a USB modem.

In my case the problem was that the modem had the echo function activated and I activated the echo in minicom too. I solved it by deactivating the echo in minicom (Ctrl+A E)
