If you want to transmit binary files with the functions dal_gfi_get_fil or dal_gfi_put_fil, you have to set binary mode first. ASCII mode is the default setting and does not have to be explicitly specified. After dal_gfi_get_fil or dal_gfi_put_fil have been called, the system is automatically reset to ASCII mode.
