Serial communication not available until opening arduino serial monitor


I am using an RFID tag reader ( and ofSerial class to comunicate with it.
I’ve found that the reader is kind of asleep, it does not write tag id on serial port until I open Arduino serial monitor. After that, it works fine.
How can I make RFID tag reader starts automaticaly inside openframeworks?


Digging on this issue, i believe i must fire up dtr and / or rts pins. Is it possible to do this inside openframeworks?

I would greatly appreciate some pointers, am a little stuck. Thanks.


If anyone is having this problem, there is a release candidate that fixes this problem: 0.9.4 Release Candidate 1
