Bypassing lock files

[Danny <mynixmail@gmail.com>]

Hi,

I have an application that uses /dev/ttyS1 and creates a lock file in /var/lock
... however I need to inject extra data into /dev/ttyS1 via a bash script ...

How would I go about "bypassing" the lock file in order for this script to
inject the data?

Any pointers?

Thank you
Danny
