Problem with Serial port
On one of the hosts, i observed that the data was being displayed recursively on the same line. There was no line feed.
I applied line feed but still it did not work.
I then changed my terminal client and switched to picocom(which is more or less the same thing as minicom).
But it gave me the following error:
FATAL: read from term failed: Resource temporarily unavailable
I tried reading the serial port (/dev/ttyS1) using other Terminal clients, but none of them could read through the port.
It's funny as only Minicom was the one which actually returned some data.
How can i be sure that the problem lies with either the terminals or my Serial port?
My serial port settings (using the command statserial /dev/ttyS1) show the following output:
