The chip that came with the modem would not allow the DCE speed to be
displayed once a CONNECT was made ... when I used ATW2 for DCE speed,
the screen would freeze and not allow any input.  The new chip solved
that problem completely.
You can tell if you have the defective chip by trying ATW2 and see what
happens.  The other way is to issue the ATI1 command.
  CD04.08 - MM03.18P5 - SP 03     <--- bad chip
  CD04.08 - MM03.26P5 - SP 03     <--- good chip

That is really strange!  How do you know what speeds that you and the
BBS are connected at?  I connect 99.8% of the time at 31,200 with an
occasional 33,600 and sometimes a 28,800 to my 33.6 BBS.  Every
connection is rock solid and never an error with u/l or d/ls.
The only parameter that I have changed from the factory settings is to
set W0 (DTE speed) to W2 (DCE speed).  Works perfect out of the box both
for BBS and FAXes.
I issued this command to change and save it
    AT W2 &W0
My Init string for both BBS and FAXes is
    ATZ
Pretty simple and it works perfect ... thank goodness because there is
very little documentation available for the AT command set.
Bye for now ... Bob
