Wake-Up Characters
The microFlash automatically goes into sleep mode in the number of
second s you speci fied usi ng your mic roFlash C onfigura tion Progr am (see
Chapter 3). Thus, you must wake up the printer for it to receive data and
print. To do this, you may program a wake-up character sequence into
your hand-held device. Program the wake-up character listed below at
least six times for baud rates of 9600 to the RS-232 port. You will need
more wake-up characters for faster speeds. No wake-up characters are
needed for IrDA. For ASK/Pluse about 150 wake-up characters are
needed at 9600 baud.
The first character sent wakes up the printer; the next few null characters
will be lost during power-up.
