Hawaii, latencies and 28.8s?

by Bill Cranst » Sun, 28 Apr 1996 04:00:00

Hi all.  I have a 14.4 modem and typically get 0.16 latency figures
whenever I join races.  I was wondering what latencies you 28.8 owners
typically experience?

Thanks,

Bill.

I have a USR 33.6 Sportster (connecting at 19.2), and I haven't had a
latency higher than .11 seconds yet.  Usually get .10 seconds.  I guess
it helps that I live about a block from my local Bell South switching
station (or whatever they call those buildings) and have new phones
lines connecting me there.

I can't race at all with my 28.8k modem , latency = 0.25 seconds. :-(

But I don't think the modem's the problem. It's either the local phone
system or a bug in Hawaii.

Latency and baud rate generally have nothing to do with each other. I
could see 28.8 owners having *higher* latencies, however, as the modem
probably has to do more processing to do the magic it has to do to achieve
the high baud rate over voice-grade phone lines.

One thing to try is forcing it to a 9600 connection. I get consistently
low latency times (.03, .05, .10, .11, or .13) everytime at 9600. I'm
using a Practical 288. At 288 it gets bad latency times. I can improve
them further by turning off the data compression and error correction.

Hope this helps some... or at least gives you some things to try.

Thanks Bill, I just tried that actually.  No matter what modem init
strings I use, the latency stays the same. Perhaps I'm using the wrong
syntax for the init string?

I've tried, for example, AT&F1&N6&K0&B1. My modem (USR Sportster
28.8)defines these extra codes as:

&N6 Sets connect speed to 9600 baud
&K0 Data compression disabled
&B1 Fixed serial port speed

Given this, is my above syntax (i.e., appending these codes to the
AT&F1) correct?

What's error correction? Is that the "Sets Error Control (ARQ)"
option? i.e., &M0 to disable it?

I have a USR 33.6 (28.8 upgraded) external and this is my init string:

        ATZ AT&K0&M0&B1&N10 ATS11=45

Last nite I got a latency of 0.13 (19.2k bps)

What does &F1 do?

I get 0.10 - 0.12 latency on my 28.8 (Sportster).

How in the world do you guys find out what your latency is? I've never
heard of anything that shows this...is it software? do you need some
special 'phone company only' latency meter or something? I'd love to find
out what I'm running on my slow-***system <G>

Hi John,

I tried your setup string and for once I didn't get the slow latency
error (which is a relief - I was getting *real* tired of that
message). Now I get a "Remote not available (timed out)" error when I
try to race (although it is still connected - it returns to the Hawaii
race menu and scheduler no problem).

Do you have the Track Pak?  If not, get it.  It will patch your existing
NASCAR.EXE file to alleviate some modem connection bugs.  If you do already
have the Track Pak, I don't know how much help I can be.  It may have been
something as simple as a problem on Hawaii's end.

FYI, You HAVE to have the Track Pack in order to use Hawaii.

I usually connect with 0.10 latency at 28.8

Thanks, I do have the track pack. Maybe I'll try re-installing it.
