Como hacer salto de linea sin que se borre los datos recibidos
Publicado por angel uvalle (1 intervención) el 07/12/2019 17:45:12
quiero que me ayuden con este codigo este recibe los datos por medio de serial port este es el codigo completo pero me faltan unas cosas, primero que no borre los datos recibidos quiero que se mantengan mostrados y segundo que hace un salto de linea automaticamente cada que reciba los datos.
