PSC Question

I very much like the idea of the PSC and looked up the spec which says
it works by accepting multi-byte sequence serial commands. However I
have a coupla dumb questions.

I presume these are "async" data bytes, with start and stop bits? If
so, is there any need to send the commands as a continuous stream of
bytes, or can the bytes be entered individually (e.g. from a terminal
keyboard or similar {at TTL levels} ) for say manual off-cpu testing)
with long delays of up to several seconds between bytes. Again, if yes,
is there any form of "time-out" which cancels a command if the delay is
too long? What happens if a command is sent to a different
device/address before a command sequence is completed?
