Nov 27, 2015 at 19:52 comment added joan The problem with transmitting serial data is in the timing. The data is not self clocking and the only guaranteed level transition is in the stop/start bits. Both ends have to maintain tight, uninteruppted timing to work out where the bits are. That is why dedicated hardware is generally used to transmit and receive the data. There is little timing leeway.
