5.6 Using remote control

All the functions of the PPA5xx/15xx can be programmed
via any of the interfaces, and results read back.

characters are ignored (e.g. tabs and spaces). Replies
from the PPA5xx/15xx are always upper case, delimited by

BANDWI,LOW;SPEED,SLOW

have been implemented, (e.g. *IDN?, *RST) and all
