A serial cable is probably the quickest way to find out the info on the 3com switch. I think you need a db9 female to female cross over cable to do the job. Since Win7 doesn't have hyperterm you can either use an XP system, transport the hyperterm stuff to Win7 or use putty in serial telnet mode to interface with the switch.
Hercules SETUP utility is useful serial port terminal (RS-485 or RS-232 terminal), UDP/IP terminal and TCP/IP Client Server terminal. It was created for HW group internal use only, but today it's includes many functions in one utility and it's Freeware! With our original devices (Serial/Ethernet Converter, RS-232/Ethernet Buffer or I/O Controller) it can be used for the UDP Config.
If you want to play retro multiplayer games, most of these use short serial cable connections between just 2 computers and don't require any more hardware than the cable itself. As such I won't be covering that in this article. Some games did support modem play for gaming with friends not in the same building as you. All computers involved needed a modem and be connected to their telephone line.
The short answer to this question is, no. Out of the box, none of the flavours of DOS from Microsoft, IBM, or Digital Research supported connectivity to a network. From the early 80s there were third-party programs such as LapLink and Norton Commander to allow you to use your serial or parallel port to transfer files from one PC to another via a cable, and DOS versions 6.0 and up got two utilities, INTERLNK and INTERSVR, that did the same thing. This became a much bigger deal when laptop computers became more commonplace, and it was even pretty common to have infra-red transmitters/receivers (see \"IrDA\") built-in for the purpose of file transfer.
Some games were also programmed to support direct cable connection of up to 8 PCs, also via the serial or parallel ports. These used one of two communications protocols to handshake with other PCs: TCP/IP and IPX/SPX by Novell. You will no doubt be familiar with the former, as it's the most widely used protocol in the world. 153554b96e
