rec.autos.simulators

My brother and I both have SupraExpress 33e's.  I bought mine to be
compatible with his, so we could race and talk at the same time.
However, so far we've been unable to find initialization strings that
allow us to do this.  

In fact, using these modems with GP2 is horrible; they appear to suck up
all the CPU resources, giving 200% occupancy when run with the same
display settings that give well under 100% in single-player mode.

With ICR2, using the stock ICR2 settings for a Supra 9600 works, but
there's no voice capability.

Does anyone have init strings for these modems that will work with
either ICR2 or GP2?  Is it even possible to have voice at the same time
as doing modem play?  Can GP2 be made to work reasonably over a modem
(it does ok over a null modem; why so busy over real modems?)

Init strings from Supra's tech support have proven useless; one worked
ok in ICR2 but didn't do voice, the other didn't work at all.

Thanks for any help you can give!

As for the init-string: I presume there must be a special AT sequence
to turn on the additional voice capabilities of the modem. This has to
be documented somewhere in the manual. Try adding this command to the
string that works with ICR2 and see what happens. Also, turn off any
compression (MNP etc.) and set the transfer rate to a relatively slow
speed (14.400, f.i.). According to the manual, ICR2 doesn't benefit
from transfer rates of more than 9600. I don't know about GP2 in that
respect. Anyway, I think that a lower transfer rate should also lower
the amount of CPU resources the modem consumes. I hope this helps a
little.

I have played, and still do play, gp2 over a modem link, and the game
plays ok?

The manual and technical supplement to gp2 explain in some detail the
options available to modem players.

Ideally the graphics and frame rate should be lowered as much as possible
to help speed up the link.

The baud rate should be set as high as possible, (and remain stable, eg:-
38400?)

You should not have any editors/patches etc loaded with gp2, it should be
a *clean* copy.

You should use the "gp2 use16550" command to start gp2, as this forces
gp2 to use the extra facilities available in a 16550 uart chip, (gp2 only
uses the old 8450 uart by default).

The initialisation string for your modem should turn OFF error checking
and compression, as gp2 carries out these functions itself to maintain
*realtime* racing.

If you do all the above, at both ends of the link, the game should run ok?

However, you should bear in mind that gp2 is a cpu hungry game, there is
no getting around that fact? and gp2 will *never* run as fast as it
normally does, while in a linked game.
It is also worth noting that the speed of your cpu, memory, modem, and
hd, all have a bearing on how fast the link will be?

Hope the info helps, happy racing......
