IPAQ 212 not working with .NET serial code

Guys

I wrote a program to display serial input string with embedded visual basic. Use this serial CF card RATOC Systems International,Inc : Serial I/O(RS-232C) CF Card CF60U . And everything works fine on IPAQ HX2190, HX2490, HX2790. :approve:

Then problems with IPAQ 212.

I am expecting this serial string

Code:

2008 09 11 18 36 48   -15.5    59.2    99.1  25.5  25.5  25.5  27  27  26 100   77.6   0.8   0.4  2.1  0.0  0.0  25.64  0.000    0.000  14.2   1.0    4.0  27  28  27

But the serial string I received is shortened intermitently like this

Code:

2008 09 11 21 14 48    51  25.5 28  26 1 0.0  1.9      0.2   1.027

2008 09 11 21 15 03   -708  25.5    26 100.0  2.3      0.0   1.0  

2008 09 11 21 15 13  -1085.5  25.   80.8  0.3  0.00    0.  4.0  26  27  27

2008 09 11 21 15 18   -171  25.5 27  26 1 0.0  1.00    0.  4.0  26  28  26

2008 09 11 18 36 48   -15.5    59.2    99.1  25.5  25.5  25.5  27  27  26 100   77.6   0.8   0.4  2.1  0.0  0.0  25.64  0.000    0.000  14.2   1.0    4.0  27  28  25

I thought properly evb3 is a old language and windows mobile 6 doesn't like it. So I tried Basic4PPC which uses the latest .NET compact framework Basic4ppc - Windows Mobile programming and Pocket PC Development , and problem should be solved.

But the same problem stills occurs!

The vxHpc hyperterminal in the PDA is receiving the string correctly at 9600 bps 8n1. Cambridge - vxHpc (Telnet / Serial)

What is wrong? I am eyeing the Ratoc serial CF card... but I could have overlooked something, some settings maybe....

Advance thanks, guys.
