Can I use PowerShell to automate, as a batch script, a procedure on a windows application, as HyperTerminal

Hi all!

I was looking for tips about to use PowerShell to run a batch-script that automates a procedure, that normally I execute with HyperTerminal, manually.

I know that some program, as Excel, can be automated to create a document and work with it, via a batch script.

For job reason, sometimes, I need to use HyperTerminal to connect to a modem; to send it some commands and then to close the connection.

I would like to know, if I can use PowerShell to do that procedure in a job task, automatically. And, if yes, how I could do.

Thank you.
