G'day David!

 db> Yes!  I'm trying to collect a list of NetComm modems that have a

 db> broken "%L0" (report receive level) command;  so far
about three (3)

 db> M34F modems *constantly* report a receive level of -50dBm, no matter

 db> what. 



I can't say I ever really noticed this problem before (I'll explain why),

but now that you mention it I see what you mean.



I don't think the "%L" command is broken, per se, it just isn't
updated all

the time - although issuing the command itself should be enough to update

receive level.



I found that the "%L" is only updated after a
"AT&V" command is issued, and

then is not updated again until another "AT&V" command is
issued.  Note,

this value is held even after the modem has been switched off!



I tried "%L" after the "&V" command in several
different circumstances and

here's what I got...



 050  -  After power-up

 049  -  Off-hook ("H1")

 017  -  During self-test ("&T1")

 023  -  During a 28800 bps V.34 (LAP-M/V.42bis) connection

 

 db> I'm collecting output from "ATI9#V0I6#V1" so that I can
present it to

 db> NetComm and say, "Look across all these models and versions - and fix

 db> it!" 



Here's mine FWIW...

I will be mentioning this to NetComm ASAP - it should work better than this!



If you want to tell someone at NetComm who can actually do something about

it, e-mail mattr{at}netcomm.com.au (Matt Rothschild).  He's in Technical

Services and he liaises with NetComm's R&D on such matters.
