Lpc2000

Hi,
I have a strange problem. I have two MCB2100 boards from Keil where 
one is transmitting data out on the COM1 and the other is receiving 
data on 
the COM1.
If i put a cable between them the receiver part writes the data out 
on the attached display very fine.

I connect my wireless RXQ1(in transmit mode) adapter with attached 
RS232 converter to transmitting MCB2100 kits COM1.

In the other end I find out that the data is received fine by 
attaching the RXQ1(in receive mode) via an RS232 converter to at PC 
that runs Hyperterminal.

I should now be able to attach the recieving RXQ1 with attached 
RS232 converter to the MCB2100's COM1 and write received data out 
onto the display.

Well, whenever I do that the LPC2129 freezes totally. I have to 
unmount the RXQ1 and reset the whole MCB2100 kit again.

How can this happen (mark that it worked with cable between the two 
kits)?
