Please have a look and drop some advice! Thanks

I presume serial1 us the default console. (read it somewhere, am correct?)
The cpu pinout:
R8822: PQFP
pin desc
001 RXD0/PIO23 002 TXD0/PIO22 003 RTS0/RTR0/PIO20 100 CTS0/ENRX0/PIO21098 TXD1/PIO27
099 RXD1/PIO28 062 PCS3/RTS1/RTR1/PIO19 063 PCS2/CTS1/ENRX1/PIO18Now is this as straightforward as it looks? Do I just connect as follows?
9pin serial --> cpu 3 TxD --> 099 rxd1 2 RxD --> 098 txd1 7 RTS --> 063 cts 8 CTS --> 062 rts (I dont even know what to cross for rs232, or do I?!)Well, theres and LQFP diagram with a different pinout. What's that about?
The exact codes on the chip: RDC R8822
0322-D-QF 6U-FGSNPI read that I can just send a ^C to the console during bootup to interrup the process.
Since I have only worked with PC's in the past, I would greatly value an advice/hints/info/directions you could give me for gaining access to th box console so I can see how it works and maybe add something useful!
Thanks so much...
