The unipolar transistor has a negative polarity or a positive polarity in accordance with the first terminal or the second terminal electrically connected to the unipolar transistor.

You first enable the console terminal (TTP) and associate the programmable asynchronous line controller (PAS) and magnetic tape controller (MT) to avoid device number conflicts.

First, here are some additional features that tput provides: extracting terminal information such as the devices, the number of columns and rows, and clearing data from the screen.
