You don't say anything about your application, so it's hard to offer advice. If the process is run when you log in via that serial port, you could do a ps, look for that process, and look for what device is running it (like pts2, tty0, etc.).

Serial port devices are: /dev/ttyS0, /dev/ttyS1, ...

I think the standard device names for serial ports under Solaris are /dev/ttya, /dev/ttyb, etc. Process names are another matter, and as far as I know, do not depend on any device names.

In my application,I am conneting a UPS and I have to monitor it via getting and sending the information using serial port or contact-closure.
So It should read the data from the UPS.To do it,It should start the process to communicate with the UPS.
So I have to find out that process is bieng stated or not??
For that,first I need to know the process name...

So Please help me out to getting the process name ?

Thanks in Advance ...

Well,.. eh, nt very clear what you want to hear from us. If you write a program, you get to decide what the name of de process will be. If you did not program it yourself, what was the command you type in to start the process? If you just installed it from the UPS vendor and is started automatically, have a look in the manual, the README that probably came with, etc. etc.

Further to Hko's comments, your UPS monitor should be no different from any other process, and that it talks to the serial port is mostly irrelevant. If you have lsof installed, you can run that, and find the PID(s) that have the serial port(s) open.

Did you read the instructions that came with your UPS?? There's probably a configuration file that you have to edit, to put in the correct serial port name.

You mention "my application". If this is something you've written, you should certainly know how to change serial port names...
