Does exist a library like SoftwareSerial which could receive data from different pins(=serial connection) at the SAME time?i think that this is possible, at least with low-medium bitrate.
Thank you for ur time,
marco
I'm not aware of one (which doesn't prove much) but I suppose it could be done with low bit rates and pin-change interrupts.
Thank you for your response 
when I get a bit 'of time, I'll try to modify the library
