I have up and running Rshell (Thierry Godefroy) BBS System on my Q68 using Retro Wifi SI and you could do the same.
No need of TCPSer or other PC Internet aware, considering that with Retro Wifi SI the QL is Internet aware.
The Retro WIFI is giving an IP address to the QL and is able to answer to incoming (TCP/IP Internet) call.
The BBS is up only for my personal use, using DynDNS I can reach it when I am abroad with my SMSQmulator running under MacOSX
There a list of connectable of Internet BBS shown at:
My BBS ran on a QL with Qbox or Pbox as the BBS software. I thought that the BBS system had died and most SYSOPs (BBS Owners), had moved to web based systems.
Which begs the question, should I get my BBS up and running again or convert it to a web site?
I want the BBS running on a QL based system, so some sort of serial connection to am internet aware computer. Maybe a Raspbery PI and use TCPSER, see this link
