Why does the arduino not work immediately on power up? Even pressing the reset button on the arduino doesn't seem to solve the problem.Baud rates are matching, 8n1 config.I haven't bothered posting my program as it happens with any program, regardless of peripheral devices attached.
This is fixed if I open up the serial monitor, which I think must be restarting the arduino.
I have a USB powered Arduino Mega 1280, which I tend to monitor using Cutecom instead of using the serial monitor
Okay I think I figured this out- turning on hardware handshaking in my terminal client seems to solve the problem!
