Hi, wanted to rec in at 4800b and tx at 2400b, is it possible (not a mega). serial begin function defines both rec and transmit at the same speed.
Thanks,
k

I suspect not, but the answer is inside the hardware serial library in the Arduino core. However there is nothing preventing you from using the hardware serial to receive and use the software serial library ( on any pin you wish) to transmit on a different baud rates.

Just across the pond from you. California, San Francisco bay area, little town called Hercules. Maybe on a clear day with no fog I could see your house? :wink:
