GP2 Modem Help Please

by Michael Radclif » Tue, 24 Sep 1996 04:00:00

Need help getting modem play to go faster!

USR 28.8 and Practical 28.8
P75 (24M, Mach64/2V) and P90 (64M, Mach32/2D)

Tried various inits.

It seems that who ever makes the call, their machine has about double
the processor occupancy of the other.

To get the game to even feel playable we have to turn off all details
and run with a frame rate of 10fps.

Not much difference when other drivers are turned off either.

Any suggestions would be greatly appreciated.

Mike

Are you running in SVGA? Sorry, but you will have to try in VGA, for SVGA
modem-play you need at least a P120 (maybe a 100 might), and still have to turn
off most things at an fps of 11.8-12.1 .
BTW, in one of my reply's, subject "Re: GP2 slow-motion with modem !?!" , you
might find an init-string.
Mmm, wait, I'll just copy it here:
 Are you using a standard init-string ? I guess so, since I (and also
others in ras) found it to be terrible and we (my friend and I) tried the
string we used in Doom, what was a major improvement.
If you have a Rockwell-based Hayes-compatible modem then one of the
following init-strings might work :

  9600 : ATS37=9N0S46=0&Q0&K0%C0 ..(Zoom 14k4 fax/modem) ............modem fixed at 9600
  9600 : AT%C0\N0B8 ...............(markless 28k8 fax/modem) ........modem fixed at 9600
  14k4 : ATS37=11N0S46=0&Q0&K0%C0 .(Zoom 14k4 fax/modem) ............modem fixed at 14k4
  28k8 : AT%C0\N0B15 ..............(markless 28k8 fax/modem) ........modem fixed at 28k8
  28k8 : AT%C0\N0&K0 ..............(Dynalink 1428VQH 28k8 fax/modem) modemspeed determined
                                                                            by negotiation
  If you need the strings with B8 or B15, the value sets the speed,
  and 10 or 11 will set it to 14k4 (I don't have this modem, so I
  don't know the exact value for sure), you should be able to find
  this in your modem-manual.

  (In all strings the 0's are zero's, not capital o's)

All these init-strings turn of datacompression and DTE/DCE-flowcontrol.

Keeping the speed at 9600 might also help.

The graphics-settings I'm using are (other than Monaco) :
  While not linking : SVGA, Fences, Track, Hills, Trackside objects
                      No plot and no texture in mirrors
                      All trackside objects
                      Estimated framerate 17.0 , I set it at 13.4
  While direct-linking : SVGA, Fences, Hills, Trackside objects
                         No plot and no texture in mirrors
                         All trackside objects
                         Framerate set to 12.8
  While modem-linking : Same as with direct, but fps set to 12.1 or 11.8

When you're using two different Pentiums, then the slower must be the
leader. The 'follow'-er gets a hard load to pull and probably will let
off steam every now and then.
While in menu's pressing Ctrl-M brings up a chatwindow.

From what I've seen, the most powerful machine must initiate the call.
Set your modem string to turn off error correction as this slows comms.
Also run gp2 with the use16550 option (very dumb!!! The default is to
use the old serial port, but who owns a PC that can run GP2 with the old
cards!!!). Check your tech manual for more  info.
