Actually, the IPC uses 8-pin Mini-DIN connectors for its serial ports. http://www.sunhelp.org/faq/sunref2.html > ** What software should I use on the Alpha box ?

Minicom is pretty silly because it combines terminal emulation and communication functions in the style of corresponding PC programs. (It's roughly a clone of Telix for MS-DOS.) On a Unix box you already have a terminal, no need to insert an emulation layer. A simple communication program such as cu(1) or tip(1), or kermit(1) from the ports, will do. > I suspect that there are non-standard serial ports on some Alpha > machines Not that I'm aware of. > for the following reason: I once had a Multia, which is basically > a NoName board in a small box.
