An evolution of the API is needed, probably in the next version.

Hi all,

I searched buf couldn't find the defaults for parity, data bits and stop bits...
Can anyone please provide the link to the document where I can find this info? 
Thanks!

Is there any way to add this to the project's documentation? I'd be happy to 
help...

By the way, this is an awesome project! Kudos to all the developers.

Hi nimshk, 
I recently had the same problem, i found these parameters to work:
DATABITS = 8, 
STOPBITS = 1, 
PARITY = NONE

Hi felipeko,

How did you set the databits, stopbits and parity?
Which files did you modify?

I didn't find any solution. How set "even parity" on serial port?

Sorry, didn't have much time to update the project.

The port is configured as 8 bits per character, 1 stop bit, no parity bit.

To modify this default setting, you have to modify the native code as explained

code in  SerialPort.c
