UART in command mode conflict with GPIO pin
I made a project with UART to try high level APIs for command mode. UART clock is derived from VC3 for 1200bps. The code is from the UART's data sheet. Rx input is connected to P1.2 (HighZ) and Tx Output is connected to P1.4(Strong). Everything works fine. But when I change P1.6 mode from HighZ to StdCPU/Strong it stops working. The initial message is sent but it dosn't receive any more. The code has not been changed at all. Can somebody tell me what's wrong?
