Paul, at 15:50 on Feb 03 1996, you wrote to Bill Grimsley ...

USRs are not like all other modems.  Lots of the S registers and other
variables are quite different to other modems.  This is why we have modem
setup strings so we can configure our software to match the particular
modem we are (ab)using.

PE>> Maybe I should have said that a little more graciously:

BG>> Nope, there's nothing at all wrong with MY comprehension.

PE> Apologize when ready.

BG>> Yep.  It just doesn't permanently write that value to 
BG>> NVRAM, that's all.  

PE> Aha, the man suddenly understands what auto baud rate detect 
PE> is in this context.

PE>> It decides to send "RING" to the computer at a rate other

BG>> Operator error perhaps?  

PE> Nope, any modem designed to send characters to the modem at

The Courier is NOT faulty in this repect. That is how ALL Couriers behave.  

Locked baudrate means LOCKED baudrate.  In a locked baudrate situation the
rate isn't supposed to change.  There is no mention (that I can find) in
the manual to support your theory.

The only reason it accepts your 38400 AT command is in case you wish to
LOCK the baud to some other rate with AT..&W

BG>> or (more likely) the last SDL didn't "take" properly.  That 
BG>> has been known to happen before.

PE> I've just done a reload, just rerun the test, same thing.

Because that is how it is designed to behave.

BG>> It's specific behaviour is controlled by the &Bn command.

PE>> Yeah, and I've got &B1, locked com port.  With "OK" coming 
PE>> in at a different speed to "RING".

The ring is coming in, as designed, at the speed stored in the NVRAM.

BG>> The &B1 setting is "correct", but I don't understand what 
BG>> you mean when you say that the incoming RING is at a 
BG>> different rate.  If both your modem and your serial port 
BG>> are locked to say 57600 bps, that's the speed at which the 
BG>> PC is communicating with the Courier, and is totally 
BG>> unrelated to the caller's speed, which is completely 
BG>> irrelevant from your POV.

PE> My modem has &B1, which means locked com port.  I can send 
PE> AT commands at 38400, and get the response at 38400, long 
PE> before a connect.  Now the USR detects someone is trying to 
PE> ring me, so it tells me "RING".  Only trouble is, it sends 
PE> that at the speed of the last NVRAM save.  Tell me the bit 
PE> that you don't understand.  Try to understand, Bill, I know 
PE> what I'm talking
PE> about.

BG>> I say again...

BG>> ===========================================================
BG>> ===========   &B1   Fixed rate.  Default.  The modem always

PE> See, the rate of my terminal is 38400, not 57600, in the 
PE> tests that I was doing.

PE>> What we CERTAINLY know is that the Spirit was far more 
PE>> robust with this REAL-WORLD modem.

BG>> Oh crap.  If you had a genuine grievance with the Courier, 
BG>> I'd go out of my way to help you solve any legitimate 
BG>> problems, but I'm almost 100% convinced that your 
BG>> "fault-finding" is little more than a childish exercise in 
BG>> oneupmanship, and I for one am no longer interested in 
BG>> playing your silly games.

PE> They are all legitimate problems. 

BG>> My last piece of advice to you is to give the Courier back 
BG>> to Paul, then 

PE> It looks like Paul Markham has saved me $175.  Thanks Paul!

BG>> look around in Aust_Trading for a second-hand Spirit, 
BG>> seeing as how you like them so much.  As far as I'm 
BG>> concerned, you'll deserve each other.

PE> And you know that's a blatant lie too.  I was screaming 
PE> about the Spirit whilst you were still in nappies (or a dress 
PE> at any rate). 

Please have the modem sent here where I can test it under the conditions of
a "perfect" phone line and an experienced operator.


David
ps.  Why is this portrate thing a problem? If you are running in locked
port mode, you are running in locked port mode.  Why would you wish to be
changing the port rate to something other than the one you have locked it
at?
