[iPAQ] Problem when connecting IPAQ hx2790(wm5.0) to Linux(fc7 2.6.21) via the serial cable

Hi,
        I'm trying to connect my 2790(wm5.0) to Linux (fc7 2.6.21)via the serial
cable.here is the way i follows :
http://handhelds.org/minihowto/wince-link/.while I've encountered several
problems:

1. I find no way to finish the WinCE Configuration because i can't find
way to creat a new direct connection on wm5.0(i can't find 'Start/
Programs/ Communication/Connections/PC Connection/Enable Direct
Connections' etc.. ).then how can i config the wm5.0 (so-called wince5.0)
to make the "Direct Connection"?

2. Leave the configuration on wm5.0 alone,here's my config files on Linux:

/etc/ppp/peers/wince

--------------start---------------------------

  /dev/ttyS0 115200 crtscts debug
connect '/usr/sbin/chat -v -f /etc/ppp/wince.chat'
noauth
local
nodetach
90.0.0.1:90.0.0.2
---------------end-----------------------------

/etc/ppp/wince.chat

--------------start----------------------------

TIMEOUT 3600
"CLIENT" "CLIENT\c"
"" "SERVER\c"
----------------end----------------------------

when i tried to connect them with "pppd call wince",it was terminated
after a short while of connetion.and here is the log:

----------------start--------------------------

Serial connection established.
