[hcflinux] Speakerphone with Conexant 06834-11

[George Bell]

At the conexant chipset modem for Linux website there is a good pdf 
manual for all the AT commands and S parameters.   There are many S 
parameters that can be set, using the command Sn=x where n is the 
parameter number and x is the parameter-usually an integer but can be a 
string too.  As I recall, a parameter can be set for the amount of time 
the modem will wait from the time it goes off-hook to start dialing. You 
could try playing with this parameter.  There are others you can 
experiment with as well.  In the manual there is a long list of all the 
parameters and what values, or ranges of values, they can be set to. 
As just a quick and dirty test, you can also just try inserting commas 
into the dial string as such: 
ATDT,555555555555 or ATDT,,5555555555555   etc..

each comma will introduce a delay set by one of the S parameters.  The 
default is 2 seconds I believe.

Good luck,

GEorge
