Quick Python Module Location Request

The pubsub example module works perfectly ! ( still running afte 4700 iterations )

Would you direct me in to the Python3 module in which sendText is located?

        interface.**sendText**("hello mesh")

I did a full emacs Find-Grep-Dired, yet, would really appreciate just the key module name.

I would like to document the options in that module. And if smart enough, add one.

     Thank you,  Bradshaw piRshared.org. Buzzards Bay, MA
