Yes. I suspend minicom.

Yes. I muved up io.h and the compilation finishes good.

I understand, and I verified the commenting sti(); a reset is generated.

I have to add:
1) I'm using sh SCI port and not SCIF;
2) to communicate with the extern world I need a connector simulating the 
full rs232 connection (pin 1 and 5 of the DB-9 connector connected togheter), 
so I have:
PC ---- connector ---- cable ----- my board

3) If I connect my linux PC to a wi98 PC instead of my board and I run 
iperterminal, when I run "gdb) target remote /dev/ttyS0"
I see 
+$Hc-1#09$Hc-1#09$Hc-1#09$Hc-1#09---+$qC#b4$qC#b4$qC#b4$qC#b4---+$qOffsets#4b
$qOffsets#4b$qOffsets#4b$qOffsets#4b---+
Is it right?

Thanks.


P.S.
After suspending minicom I run the following steps.
Are they correct?
