Diagnostic Mode code?

Does anyone know what the code to get into the diagnostic screen of the i515 is?
I can access boot information by pressing down the volume rocker keys, and pressing power, and I can also go into testing mode by entering *#*#4636#*#* into the dialer, but none can help me set up a diag port for use with apps like QPST, etc. Anyone have any info on this?
Hi,
Anyone found out about the diag mode?
There is no diag mode. Only the code he mentioned above.
Does it install any usb modem?, I mean if we can use some kind of hardware virtual serial port.
same as in motorola programming work. This phone need to be researched.
