G'day Netcomm,

We have a Netcomm roadster modem that was being used as a dialin modem on 
our Internet Public Access Site. In the time that it was being used for this
purpose, we had several problems with it. Most users were able to connect OK, 
but in general the modem did not perform as reliably as the other modems we 
have (Maestro 33.6Kbps and Avtec 14.4Kbps).

In particular one of our users never successfuly connected to this modem. This 
particular user has an Avtec Megamodem, which I understand to be a re-badged
cheaper version of the Roadster. 

Other assorted modems connect OK to the Roadster, but the Megamodem does not. 
However, the Megamodem connects OK to our other modems.  It is strange that 
the Megamodem->Roadster combination causes more problems than the 
Megamodem->Othermodem or Othermodem->Roadster combinations. Note that all modems
involved were "AT&F&W"ed.

When attempting to connect to the Roadster with the Megamodem, there is a 
distinctive sound to the negotiations that is absent from successful connections 
with other modems. The only way to discribe it is; 
"Wheeeeee, Whoooooo, Boink, Boink, Boink, Click", NO CARRIER.

I have read somewhere (sorry, can't find it now) in a newsgroup that this noise
is associated with some fax tone or another, and that this can be turned off with
some (undocumented?) Roadster AT command. Unfortunatly we have not tried this, 
because I can't find the news article :-(.

The details of the modems are;

Netcomm Roadster 28.8K V34
Model No: 	AM3450 	REN 1.0
Serial no:	519800498
ATI6	RC288DPi Rev 05BA
ATI9	Roadster 288 V1.200-V34_DS-0.34 (C) NetComm Ltd. 1995

Avtec MegaModem 28.8K V34
Model No:	unknown
Serial No:	unknown
ATI6	unknown		
ATI9	Avtek MegaModem 288 V1.200-V34_DS-0.35 (C) NetComm Ltd. 1995


I understand that you have some sort of upgrade offer for the Roadsters to 
upgrade the firmware and bring them up to 33.6Kbps. Will this solve the problems
we have been experiencing? Should the user of the Megamodem also get some
sort of firmware upgrade? How do we go about getting the upgrade done?

Thanks,

ABO
