Yep, I picked up a U.S. Robotics 56K USB (no serial ports on PC’s these days) modem on sale just in case we are forced to return to BBS days! Next step HAM equipment.
This Dell laptop I’m working off of now is the first computer I’ve bought without a modem. Just always insisted on having one as a basic configuration in the past. Now that you mentioned it, lol, those old modems did connect via serial.
