Hurray. I was able to connect via TCPSER and following a guide already on Amiga.org. I changed my settings to 'tcpser.exe -d /dev/ttyS4 -s 19200 -l5'
I'm on At2k. Thanks for your help guys.
Edit: I'm getting a tiny bit of graphical problems such as some possibl ascii characters not displaying properly, but I might be wrong. For example when I was creating a account it showed "Your nickname zz yournamehere. Also, the main menu name looks a bit different, but it could just we the BBS, but I'm not sure.
