for other device to take effect. Settings are:
Serial Port:
IrDA(Infrared):
ASKIR(Infrared):
SmartCard Reader:
RxD, TxD Active
Set the receiving and transmission as active high or active low. Settings:
"Hi Hi", "Hi Lo", "Lo Hi" and "Lo Lo".

dard Parallel Port, choose "SPP." To operate the onboard parallel port in
the EPP mode, choose "EPP." By choosing "ECP", the onboard parallel

onboard parallel port to support both the ECP and EPP modes simulta-
neously. Settings are:
SPP : Standard Parallel Port
EPP : Enhanced Parallel Port
ECP : Extended Capability Port
ECP+EPP: Extended Capability Port + Enhanced Parallel Port
