Download Request
A computer can use this command to inform the 1775–KA module that it
wants to do a download. If the 1775–KA module grants the download
privilege, the computer may begin issuing privileged writes. You should,
however, issue a shutdown command first. If a different station already
has the download privilege, the second station is denied the privilege.
The function code is 5.
