These parameters can be passed straight to DOOM II, or passed to IPXSETUP or SERSETUP, which then passes them to DOOM II.

To use hexadecimal, such as the number 0x3f8, you would type "-port 0x3f8" -port. -PORT sets the COM I/O port that SERSETUP uses to communicate with your modem.Just in case your 16550 UART is acting up at the higher speed. -8250 tells SERSETUP to set the UART to 8250.-COM1, -COM2, -COM3, -COM4 specifies what COM port your modem or serial cable is using.-ANSWER puts your modem into Answer mode so someone can call you and play DOOM2.-DIAL tells the program what number to dial, if you're going to do the calling.

When you want to play a modem or null-modem game, you need to run SERSETUP.EXE, which is the device driver for DOOM2's serial communications mode. By setting a different port, more than one group of players can play DOOM2 on a single network. -PORT sets the port to play DOOM2 Multiplayer on the network.If you don't specify the number of nodes, the default is 2. -NODES starts DOOM2 as a network game and sets the number of players who are going to play.When you want to run a Network game, you use IPXSETUP.EXE, which is the device driver for DOOM2's network mode. Consider using Wine to run Windows programs and games.
