I'm sure this question has been answered before, but I can't find the right info on this so bear with me. What's the best way to connect to a BBS using an Atari 800 without a phone line? Do I need a modem still or can I use a cable to connect to my PC have it act as the 'modem'? I imagine the solution involves Telnet, but I'm not sure exactly what I all need to give this a try. What software/hardware do I need?
I currently have an Atari 850 interface, an SIO2USB and SIO2PC (serial) devices. I also have a PC with serial ports and an internet connection (Windows 10 and Linux).
