Hi, I have a strange problem. I have two MCB2100 boards 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)?
