I haven't been able to see any data on the Kermit screen.

ok. I think I set all the necessary parameters. I will configure them once

The device has a RS-232 / Printer DB-25 pin outlet. The device manual mentions
that I need to connect my computer (or printer) to this port. I use RS-232C
cable. I have connected the device to the serial port (DB-9) on my computer.
Should I connect it to the printer/parallel port?
