Re: New Multitech modem-blank faxes



Thanks to those who helped solve the problem of the
new multitech multimodem (MT5634ZBA).  Here is a summary of the
salient facts for the group.

Multitech was not good about calling back or following up so that
without the help of this group, I wouldn't have solved the problem.
(They were good about supplying a free eprom upgrade for an older
MT1432BA modem).  Multitech said that the modem was rated as a
Class 2 and felt that MSB/LSB reversal was an issue.  They gave
another fix for defining that in the modem setup
which I applied as follows:
ModemSetupAACmd:        AT+FAA=1+FRBOR=0        
They said to try botth +FRBOR=0 and +FRBOR=1.
However, neither worked to solve the problem.

I received a reply from ras also pointing to an MGS/LSB reversal issue.

However, the most useful response which solved the issue was:

Thanks to the group, esp Martin.
