- Another way of having your own bbs, using AGW Packet engine. HamServ is a TCP/IP Server program that runs under 32 bit windows and offers support for AX25, HTTP, NNTP, POP3, SMTP, and TELNET.
Ideally it should be run under the AGW Packet engine, with the add on TCP/IP driver, it then allows for simultaneous connects via the internet and via packet radio, but it can of course be used stand alone, in which case people will be able to connect to it via the Internet.
