You change the default escape character from 0x2B to something below 0x20

Go to the "S" Register Appendix for you modem;
look for a "S" register with the value 43 (decimal) as a default.
Change the escape value in the modem and the chat script to 14  (0x0E) 
"S2" holds the escape character for my "ZOOM" modem.
Change   +    (43)   -->   Ctrl-N    (14)
And last is to set the asyncmap to escape   Ctrl-N  (14)  0x0E

Here is the changes to  my chat script :
# /etc/ppp/chat
# change the modem default escape character from 0x2B to 0x0E
MODEM_INIT='"AT  S2=14 "' 
# get the attention of the modem,  hangup in case we were off hook.
echo '"" ^N^N^NATZ!!' >>${TMP}  


/etc/ppp/peers/<my-isp>  or  /etc/ppp/options*
asyncmap 00002000          # represents the character 0x0E or  Ctrl-N.
