Discover the program that use serial port (Sherlock Holmes Case)
Hi,
I received a server that use AIX 5.x.
This server was installed from a company that doesnt exist now, and they dont leave information about it.
I only know that they installed a program that recieve information from some tty in a special format and as it is a tty, with some baud rate, data bits, etc. After that the program resend the info to another server.
My Sherlock Holmes task is to find out what program do this task, and try to find out the special format this program use, and from which tty port.
Any clues to find out this info?
Thanks !!!
