USING SERIAL LINK

Can anyone help me, please? When I play GP2 through a serial link, connecting a Pentium 7 8 mb with a Pentium 90 24 mb, the game hangs all the time for just a couple of seconds. It is very irritating and it makes it impossible to do races against each other (in practice it doesn't hang). Does anyone know what causes the problem and what the solution is?

I have linked a P90 (8MB) and a P100 (16MB) via null modem. In my experience, the slower machine determines the game speed. This means the time will slow down (since GP2 does not leave out frames) as soon as the slower machine can't keep up anymore. I haven't experienced exactly the problem you are describing, but here are a few suggestions: - Supply as much conventional memory as possible on both machines. Basically, the only TSR you need is the CD-ROM driver. - Start the game with the option "use16550", provided both computers have FIFO chips installed. You can check this with MSD, an utility provided with MS-DOS or Win3.x (not sure about Win95). - In the connection menue, select 19200 as speed for the link. (Lower values are to slow, faster ones may be unreliable.) - When connected, go to the graphics options menue and change the frame rate. Notice how it looks different from the stand-alone version: Now, the display says something like "Suggested framerate for this machine: 21.7 For remote machine: 17.0". Now comes the ugly part: If your numbers look like the ones in my example, you have to choose *not*more*than* 15 FPS, i.e. at least two FPS less than the slower machine. Better choose 14 FPS. If all this accomplishes nothing, it is possible that a) one of the COM ports does not work properly, or b) your null modem cable is defective. Make sure the cable does not run parallel and very close to power chords - I think this can cause transmission errors (could be superstition, though... :) HTH [posted and mailed] -- We're in a road movie to Berlin Can't drive out the way we drove in

I=B4ve used a Modem to connect two computers and the calling computer = allways carry the workload. So have the fastest machine call up and = start with a minimum of gfx (typically no sky its a real cyclestealer). = also set the framerate to 14-20 fps. Then it will work O.K. Regards Robert
