The ArcaneByte RS232 WiFi Modem is a Hayes-like wireless modem for vintage computers. It connects your RS232-equipped computer to your home wireless network, allowing you to connect to Internet-based BBSes or local machines using standard terminal emulators.

Dial your favorite BBS using an IP address rather than a phone number. Or, transfer files locally or across the Internet using zmodem or Kermit. If you want to host a BBS, enable the TCP/IP listener function to ‘dial in’ to your vintage machine. The possibilities really are endless!

The ArcaneByte WiFi Modem is a hand-built device that utilizes the open sourced Zimodem firmware by Bo Zimmerman. The device requires 5V over microUSB (not included).
