"WebWith TTL serial, there are two unidirectional data lines. Each is driven by the sender, both high and low. A 0 bit is represented by 0V a 1 bit by VCC. The receiver's pin should be set to an input. So, for a microcontroller to send a byte (8-N-1 no flow control) it could do something like this: " - Ttl high
