Hi Tomas,

really works to read from serial, could you help me I want to do something on bash to read and act like a daemon all the time like keyboard input, read what nfc near and enter character... And also bash script to write on it, i have tried

WRITE=`dd if=code of=/dev/ttyS0 count=1`

in code file is the number for example 051755F

thank you in advance.
