I have unsuccessful getting 'platform_uart_read' to work. 'platform_uart_write' works just fine. I have attempted to debug source of problem using an oscilloscope. When I unplug the COM1 cable header, I am able to see receive character bits on the scope as I type into the Hyperterminal. However, when I plug the cable into the COM1 header, I no longer see the chars arriving on the RxD pin. It is as though there is a board short. Does this sound familar to anyone? Any advice would be helpful.
