how to enter boot prompt for PC's Hyperterminal?

[Gavinux Li <linux4sparc@yahoo.com>]

I connect to SPARC IPX by reading
http://www.ultralinux.org/faq.html#q_5_1 
23. How can I connect a machine for an installation
via a serial cable ?
Essentially, if there is no keyboard plugged in when
the Sun has booted, it will use the serial interface
(port A), By default it is set to 9600bps 8,n,1 
//// What kind of cable should I use. I made the
conection to PC serial port and use HyperTerminal on
PC, the cable I made is:

SPARC Port A             PC COM2
       RXD                 TXD
       TXD                 RXD
       GND                 GND
Is this the right one?///

You can force the serial console from the boot (ok)
prompt: 

   ok setenv input-device ttya
   ok setenv output-device ttya
/// Does it input in the SPARC kerboard? Otherwise how
can I enter boot prompt from HyperTerminal, How to
simulate STOP A key from HyperTerminal on PC side? ///
On the other (PC?) side running any terminal emulator
will work (kermit, minicom, seyon) 
/// If I use minicom in PC-Linux, Which keys should I
press to simulated STOP A key?///
