LOCAL
L[;addr]
Without optional address, instructs the Micro488/p to un-assert the
Remote Enable line causing devices on the bus to return to manual
operation; with optional address, places bus device in the local mode by
the Go To Local (GTL) bus command.

Un-asserts the Attention (ATN) bus signal; removes the Micro488/p
from the active controller state and allows transfers between two
peripheral devices.
3-16
SERIAL POLL
SP;addr
Performs a serial poll of the bus device specified; responds with a
number from 0 to 255 representing the decimal equivalent of the eight-
