Hi,
I'm working on
kdbg remote debugger using null modem cable.
I patched the
kernel source with the kdbg patch.Thereafter, I copied the kernel image into the
/boot directory of the target
machine. Now I have a doubt regarding null modem cable. Using 2 9 pin to 25 pin connectors,I made a null modem cable. 9 pin ends of the cable were connected to the machines(COM ports). Before going to remote debugging, I wanted to check whether back-to-back connection is proper or not. So I wrote into the COM port of the development m/c (/dev/ttyS0) and tried it read on the target m/c from the COM port (/dev/ttyS0) using "cat" command as follows: Dev. m/c: cat <file> > /dev/ttyS0 Tar m/c cat /dev/ttyS0 Unfortunately the expected is not happening. First of all, I want to know the null modem cable which I'm using is proper. Please help me in this regard. Waiting for your reply. Regards, R.Rupa |
