Hello all,
(apols for the bizarre crossposting)
I'm trying to use a couple of games (Grand Prix 2, Indycar) supporting
modem / null-modem play to play between two machines with ethernet
connections to the internet.
Firstly, I'm surprised that I haven't found any description of this
having already been attempted - and if it has been done successfully,
I'd be very interested to hear!
I've tried two similar strategies to doing this.
The first was to use net14.exe, supplied with NCSA telnet. It diverts
calls to the INT14 software interrupt (for serial communications) to the
ethernet card. You can get net14 connected via telnet to a particular IP
address by passing it ^B1.2.3.4^C. We can both make connections to UNIX
hosts using this method, and log in using kermit sending direct to
INT14, which is then diverted to telnet.
Having logged in, running IHHD (internet head-to-head daemon) means we
can set the connection up so that everything sent from A goes to B and
vice versa.
The problems happen when we actually use a game (e.g. GP2). Having set
up the connection (above), and pushed from kermit, attemting a modem
connection in GP2 somehow seems to reset the internet connection. (Just
running GP2, exiting, and returning to kermit does not).
We've tried the same thing with tnglass, a telnet which can take input
from INT14, with the same results.
We suspect that the process of initialising the modem in the game is
causing all the problems...any ideas for a solution?
If anyone has successfully managed to do this for any game or situation
requiring an ethernet connection to emulate a modem, I'd love to know.
Thanks for your help, Paul Smyth.
