You are correct. The CMMS command is supposed to keep the GSM link open during message sending in order to speed up things (due to less handshake per message). SMSLib used to use the CMMS command but it was removed some versions ago. From personal experience, using Nokia and Wavecom devices, I haven't seen any performance gain by using the CMMS command. I don't know if my implementation was right or wrong, but I didn't notice any speed improvements...
If you want to add the CMMS command again, then the sendMessage() method is the correct method to modify. This will not affect the background sending though... A question from me: do you know the "scope" of the CMMS command? I mean, once you issue CMMS=1 for how long or until what action is the command in effect?
