Java ile seri port işlemleri için yazılmış bir kütüphane mevcut ilk olarak buradaki RXTXcomm-2.2pre2 dosyadan sisteminize uygun klasör içerisindeki dosyayı işletim sisteminizin ana dizinine atınız (örn. windows için C:\windows\).
Buradaki örnek ile seri port üzerinden gelen verileri okumaya yarayan bir uygulama.
