Dear Dr. Michael Weller,
Thank you very much for your good advice to my question.
I read your advice and thought that by redirecting stdin and
stdout of the gdb debugger to my serial terminal (/dev/ttyS0),
I can communicate with debugger program. Then I tried this
method.
First, I stopped a getty process which monitors serial port
(/dev/ttyS0), bacause a getty process interfares communication
with debugger program.
Second, I redirected input and output devices for debugger
program to /dev/ttyS0 which is serial terminal.
For example:
[root@kiev45 demos]$ cat /dev/ttyS0 | gdb foo > /dev/ttyS0
After debugging, I send 'quit' command to the debugger
from serial terminal, and terminated 'cat /dev/ttyS0' process
by sending a TERM signal from console. Then a command prompt
returned to console!
Sincerely yours,
Shingo Mochinushi
