I can only speak for A-Talk III scripts, but the script DIAL command will
do the appropriate exchange, including gobbling the CONNECT string.  It will
also put the result of DIAL in the RC variable, so the Rexx script can
check for success/failure of the dial.  Of course you must have selected 
the appropriate modem for this to work.   You could also do away with
the DIAL command and implement it with:

REPLY "ATDT666-888"
ON "CONNECT" do this
ON "BUSY" goto there

etc...

Note that the RC variable is set only in later versions of 1.2 and in all
versions of A-Talk III 1.3x (x = a, b, c). 

A-Talk III has the STRING command to send input string from the host back
to the Arexx script. Look at the examples in the manual, under the STRING
script command.
