Keepalive with EMI2

Hi:

I'm using Kannel 1.1.5 to connect to a CMG SMSC with EMI2 interface. The 
mobile operator is asking me to send every 30 seconds a UCP 31 message 
to keep the connection open. Is there a way to do this with Kannel ? I 
have already made some changes in smsc_emi2.c to do this, but if someone 
has already done this, please tell me!

Thank you
