serial connection

 Maybe it is me but I cannot get the serial connection working. When I try to upload I get the message: Connection failed
Forced interrupt!


Have 2 different displays, 2 different USB to serial converters.

Connecting RX to TX and made a ground connection.

The USB to serial connectors are OK. If I connect pin 2 and 3 togeter and use a serial comm program (Hyperterminal) in the PC my typings get displayed.


Wrote a small program in the Nextions and connected them to the PC with Hyperterminal, just nothing. I'm fighting this for a long time now but cannot get it working. What am I doing wrong?
