I have to run a software which I/O is only serial, so I have installed ser2net and configured this way:
10001:raw:600:/dev/ttyS0:9600 NONE 8DATABITS 1STOPBIT -XONXOFF -RTSCTS LOCAL
On other PC, I ran telnet 10001.
I cannot send nor receive nothing from/to that ttyS0, UNLESS I make a physical loop between RX and TX pins (pins 2 & 3) on the DB9 connector on my first PC...
When I install the bridge between RX and TX, all works flawlessly, what my software sends to /dev/ttyS0 is received on the telnet screen on the other PC, and viceversa.
How can I manage to make ser2net work without loopback? I´ve tried different configs for ser2net, unsuccessfully.
