The kernel finds the port but when I echo something to it, nothing comes out of the port. I received some replies but nothing that was suggested has worked. Could someone please suggest how I can test the second serial port and then hopefully get it working. Below are the things that I have tried so far: I added SMC2 to the rs_table in arch/ppc/8xx_io/uart.c and the kernel detected the port. CPM UART driver version 0.02 ttyS00 at 0x0280 is a SMC ttyS01 at 0x0380 is a SMC I have made sure that there is the correct device nodes in /dev # ls -la ttyS* crw-r--r-- 1 root 0 4, 64 Sep 7 1998 ttyS0 crw-rw---- 1 root 66 4, 65 Dec 10 1999 ttyS1 Does anyone have any ideas where I can go from here. I am not 100% that the hardware is working so perhaps that could be the problem.
