Screen does connect to serial ports. Just open the device and append the line parameters you want to run on the port. Unlike modem dialers like Minicom, you don't have to screw around with on-hook off-hook distinctions or an intrusive TUI.
Exactly the other way around for me! I've been using screen since forever, and had no idea it could do that. Minicom I still know from the dialup dark ages.
