Mayelana nalolu hlelo lokusebenza

Inhloso lokusebenza ukulawula hardware eyihlane like Arduino, Netduino, Raspberry Pi ...
Iziphakamiso eziyisisekelo TCP / IP (Client).

UP: 0, amandla, 0
DOWN: 0, -power, 0
KWESOKUNXELE: -power, amandla, 0
KWESOKUDLA: amandla, amandla, 0
PHAKATHI: 0, 0, 0 noma 0, 0, amandla (Zero esebenzayo)

Byte Mode: 3 tikhundla kuthiwa transfered 3 bytes (default)
ASCII mode: 3 tikhundla kuthiwa transfered njengoba umbhalo ohlukaniswe yikhefana (iqedwe \ n)
Session abapholile: yokudlulisela ngasinye endaweni Serated uxhumano
Session asebenzayo: Connection never sekuvaliwe, kodwa abuye uma kunesidingo kabusha okuzenzakalelayo (default)
Zero abapholile: Ayikho ukubuya kuya zero amagugu ngemva kokukhululwa
Zero asebenzayo: Auto ukubuya kuya zero amagugu ngemva kokukhululwa
