La pestaña 'Enviar / Recibir'

Los contenidos de la pestaña de envío y recepción de archivos dependen del protocolo utilizado por el puerto seleccionado.

The Manual transmission dialog is used by ports that supports transfers, where the program can be selected from the DNC server (ex. the standard protocol).

The Directory selection dialog is used by port that supports only remote requested operations (ex. Heidenhain protocol).
