when a valid receiver level is detected (same function-
ality as AutoShutdown feature on MAX3221/MAX3223/
MAX3243).
A mouse or other system with AutoShutdown Plus may
need time to wake up. Figure 5 shows a circuit that
forces the transmitters on for 100ms, allowing enough
time for the other system to realize that the MAX3244/
MAX3245 is awake. If the other system outputs valid
RS-232 signal transitions within that time, the RS-232
ports on both systems remain enabled.
S oftware-Controlled S hutdown
If direct software control is desired, use
INVALID
to
indicate DTR or Ring Indicator signal. Tie
FORCEOFF
and FORCEON together to bypass the AutoShutdown
Plus so the line acts like a
SHDN
input.
