Break signals over uart


#1

Is there any way to transmit a break signal over UART1? I have to wake-up a device which is connected to the UART1 of my Fastrack Xtend FXT001.
Thanks for the replies in advance!

Not directly using FCM.
However, there is a “trick” to send a NUL at a reduced baud rate - which will have the effect of a BREAK.

This is described in a Maxim/Dallas App Note about their UART-to-1-Wire bridge chips; it was mentioned in this thread wavecom.com/modules/movie/sc … reak#p8220 - but the forum seems to have lost that!

Or you could use the Direct UART access…
