Locking issue with serial port

In my application,I need to monitor the devices connected through serial port in solaris sparc 9 OS.I used c and java code for it and I am able to do the same but the problem comes when I restart the system and the open my application and try to monitor it.but I m unable to monitor the devices and getting the message --

Warning: The serial port "/dev/term/a" cannot be opened for use.
Please verify that it is entered correctly and that it is not already in use.
but when I delete /var/lock/LCK..a file.I am able to monitor again.

So plz let me know why it is happening and how to solve it.

Thanks in advance..

Filesystem Hierarchy Standard - 5.9 /var/lock : Lock files
