AltSoftSerial Library for Arduino Boards

AltSoftSerial is a software emulated serial library for Arduino boards, using hardware timers for improved compatibility.

AltSoftSerial is particularly useful when simultaneous data flows are needed. It is capable of running up to 57600 baud on 16 MHz AVR with up to 9 µs interrupt latency from other libraries. Slower baud rates are recommended when other code may delay AltSoftSerial's interrupt response by more than 9 µs.

AltSoftSerial Library can be installed to Arduino IDE using Library Manager.
