SMS control for Relays

[skimask]

Thanks for that.

I'm not refering to the DEBUG command, instead, those AT commands. Can you share to me the basic principles (background) on how to extracting SMS messages from a cellphone. I find it hard interpreting your code especially those AT commands. I know that there are special registers in the cellphones to deal with. What interest me most is the theory behind the extraction of these messages.

Two questions
DEBUGIN [WAIT("+CMGR:"), SKIP 53 , DEC MYDATA]
if i understand your code correct you are expecting a byte value in MYDATA what will happen if this is bigger than a byte

2nd question
I am using a MC55 modem from siemens
+CMGR: "REC UNREAD","+27829554322",,"08/04/19,13:08:34+08"
test
if i only want to extract the cell number will this be the correct command, as what do i need to conf cellNumber and what will happen to the rest of the serial string comming in
DEBUGIN [WAIT("+CMGR:"), SKIP 16 , cellNumber]
