david, at 19:23 on Mar 19 1996, you wrote to Bill Grimsley...

Ah, right, that's what we saw, but then we had \V9 enabled as well.
db> You can't blame the M34F for all these dolts running around ignoring TFM?
db> BTW, for those who didn't already know, the Programmer's Society at the

And they're not even worth the paper on which they're printed, if nobody
bothers reading them. Indeed, all we had were the on-line help screens, no
manual in sight at all.
BG> In fact, how exactly IS it reported on the M34F?
db> See above - with \V1, you only get the last "CONNECT
28800..." line at the

OK, so it's just a straight DCE value, no EC or compression data at all.

All modems work much the same though, with the real differences being in
the manner in which their link diagnostics are reported. And their
accuracy. :)

Easy to condemn in retrospect, but we've all been guilty of something like
that at least once in our modemming lives...
BG> So your EQM is once again between 17-19, and Rx signal level is -50dBm.
db> No it's not. Ignore it, it's broken. As I said some weeks ago.
If I'd known at the time that I'd have been using an M34F within a week or
two, I'd have made a note of those inherent problems, but as I didn't...
:(
db> Bill, you gave me the impression that you were using an M34F for a test,
db> too; no, lemme guess .. just relieving yourself, eh? :-)
Davdi Drummond borrowed it from BHP for an extended test period, and
brought it around here last Saturday night for a bit of local testing.
db> If not, can you give me the full EPROM/Rockwell version numbers please (DD,
db> same for you too, please - and Paul again, too) as I want to see if there

Whilst I didn't make a note of everything, I *DO* recall that the M34F's
EPROM revision was 2.61L (does that sound right?), and that it was only
about three weeks old. Here is the active profile I used when testing the
M34F here that night:
----------------------------------------------------------------------------

---------------------------------------------------------------------------
The only changes from a normal AT&F. were as follows...
L0 = Minimum speaker volume level
T = DTMF Tone dialling
&D2 = Modem follows state of DTR
&K3 = CTS/RTS Flow Control (not &K9)
%C2 = Enable V.42bis but disable MNP-5
\V9 = Extended response codes & diagnostics
#C0 = Disable V.25 Call-Indicate tones
S000=000 = Disable modem's auto-answer
S007=060 = Increase carrier wait delay
S011=065 = Faster DTMF dialling (65mS is fastest speed accepted)
(Note also that I did NOT attempt to force fixed Tx levels at all)
