If the host detects that the LL signal is
on
and
the local loopback rest is executable, it sets
this signal on
(0).
If the host turns this signal on in response
to
the LL signal being an, the host
does
not set
this signal off
(1)
until
the LL signal is
ser
to
1.
If this signal is not set to 0 within 2
set
after the printer sets the LL on
CO),
the printer
terminates the local
loopback
test
and sets
the
LL off
(I).
The combinations of the RTS and CTS signals listed in Table 6.2 are providedfor the printer.For the RTS and CTS setup, refer to *!rator's Guide.Table 6.2 Operation by the RTS and CTS combination
