Once apon a time Bill Grimsley said, 'Re: Specifics on modem retraining' to
Simon Byrnand...



 BG> Oddly enough, the "Fallback Disabled" mentioned in the Sportster's

 BG> ATI6 stats relates specifically to the HST protocol, even though that

 BG> class of USR modem doesn't support it.  Sounds ridiculous, I know, but

 BG> this has been verified with USR's tech support themselves.



Ok, well I can put the Fallback reading well and truely into the "who
cares"

bin :-)



 BG> That problem generally only shows up during interactive (i.e.
"chat")

 BG> mode.  When transferring files etc., its V.42bis works just fine.



So far I cant say I have noticed it in interactive mode either, as well as

Internet, I do a fair bit of BBS work with it, (I dial into the BBS I run

to get my mail, as it doesnt run from home) and it hasnt played up, so

maybe I'm one of the lucky ones :-) In fact I cant really fault it,

considering all the criticisim I've heard about them....



 SB> Is it possible this specimen has later version firmware that fixes the

 SB> bug?  Here is an ATI7 dump:

 BG> [ ... ]

 SB> EPROM date             8/13/96

 SB> DSP date               8/13/96



 BG> Looks like the affected series to me, although due to the specific

 BG> nature of the problem, some people may never see it at all.  USR

 BG> recommend the use of S12=0 as a quick fix, although what the escape

 BG> code guard time has to do with BTLZ is completely beyond me.



I cant see any correlation either, I havn't bothered to fiddle with S12.



 BG> DL the text-based Sportster and Courier technical manuals from

 BG> www.usr.com, and all will be revealed (the Courier manual is far more

 BG> descriptive).  If you need to know more than that, link into the

 BG> USR_Modems echo and simply ask.



Ok, thanks for that, I downloaded both the Sportster and Courier manuals

in Word format, they are a lot better than the one I have. They are still

both extremely coy about saying anything about ATI11 however, the Sportster

manual doesnt even list it as a valid command, while the Courier manual just

says its for diagnostic purposes "if a USR technician asks you to read out

the results". Gee thanks....;-)

Simon
