It does help. Thanks a lot!
There is no serial port on my laptop, only USB ports. I saw some USB-to-DB9 cables in eBay and was wondering why such "simple" cables need drivers. Your answer clarifies that the driver is used to create a new serial port under Windows.
May I assume that a USB-to-RJ45 cable does the same job as the USB-to-DB9 cable? On the IBM P640, there is a RJ45 port functioning as serial port. It also has some DB9 serial ports. On some Sun servers such as Sunfire v100, there is no serial port in DB9 form, only serial port in RJ45 form. Therefore, a USB-to-RJ45 cable may be a better choice (than USB-to-DB9) if it is working. Am I right here?

If your laptop has USB ports you can use one of those USB-to-DB9 converters to connect to the serial port of the pSeries server. They usually comes with a driver so Windows creates a new serial port and using Hyperterminal you cna connect.
Hope this helps

iscc(7) Miscellaneous Information Manual iscc(7)
NAME
iscc - serial communications interface
SYNOPSIS
controller iscc0 at isa0
DESCRIPTION
An onboard Zilog 8530 DUART provides AXPvme-based Single Board Computers with console (CON) and auxiliary (AUX) serial communications
ports. Both serial communications ports can operate at baud rates from B50 to B38400, excluding B134 (see tty(7)).
On AXPvme Single Board Computers configured with a graphics head as the system console, the CON serial communications port (/dev/tty01) is
available for use by application programs as an additional communications port.
In the absence of a graphics head, the CON serial communications port (/dev/console) becomes the system console. When used as the serial
system console, the CON serial communications port always operates at 9600 BPS, 8-bits, and no parity.
Regardless of system console, the AUX serial communications port (/dev/tty00) is always available for use by application programs.
RESTRICTIONS
Data communications equipment attached to the CON serial communications port must be set to 9600 BPS, 8-bits, no parity when configured as
the serial system console. The iscc terminal driver enforces this restriction.
No modem control is supported for either the CON or AUX serial communications ports.
FILES
console terminal local terminal local terminal
