To export Debugging message.
If Debugging message is exported using USB interface, the Debugging message related to memorizer on the one hand can not be exported, then
If it is desired to debugging to memorizer, then need using other interface；On the other hand, the firmware version in some electronic equipments
With above-mentioned three kinds of debud modes may there is a problem of unstable, for example, BIOS adopt IBM PHOENIX series when, if adopting
With this electronic equipment of USB AccessPort, will exist unstable, the problem that usually cannot connect.
If Debugging message is exported using PMON serial ports, problems with can be produced：(1) will using PMON serial ports it is necessary to
First adapter (connector) is welded on mainboard, after the completion of debugging, also connector is removed from mainboard, time-consuming
Arduously, even if connector is arranged on mainboard during research and development it is contemplated that production cost, to the SIT/SVT stage, also can be by
Connector removes；(2) connector materials are special, obtain difficult, and have mechanical interferences；(3) and not all electricity
Sub- equipment is both provided with PMON serial ports, and therefore versatility is poor.
If Debugging message is exported using WLAN/WWAN slot, problems with can be produced：(1) need to arrange WLAN/
WWAN keyset, after keyset is not easy to obtain, and WLAN WWAN pin slot in future changes, keyset must remake；
(2) WLAN/WWAN keyset runs into mechanical interferences problem sometimes, and such as keyset is bigger than WLAN/WWAN module, can make
Become to connect difficult problem；(3) in overall design, needs are placed on C or D door to open WLAN/WWAN slot can
With the place being plugged, the difficulty (for example, can lead to tear machine open) of debug erection otherwise can be increased；(4) not all
Electronic equipment has this design, such as ThinkPad X1tablet just no this design.
