hi, every one.
I'm working on a project to connect plc from OMRON cpm2a with siemens tc35i gsm module. I try to connect with the TC35i from local modem via hyper terminal, and i established the connection.
Next step was to comunicate via cx-programer 7.2 with gsm module and plc. but it tells me :
"The selected port is used by another application"
Can any help me what to do? Does i need some at-comands for my modem, to be configure, to call without ring tone, or any.
