First of all, i want to thank you everybody who make this project useful. Secondly, my english is pretty bad and i am sorry for that. I am trying to learn.
I have some questions. But before that, let me say that i read all of this topics;

I have this board;

Still, i could not set it up.
I realy want to tell what i have done so far. But bucause of my english, i am having hard time when try to. Can some one show me, how can i build this up. I guess my board is maple mini clone.

Let us know if you hit any snags.

*couldn’t resist*
I finaly make it.
If i want to use full modem uart, how can i do it? Is it same as arduino (i dont know yet, if arduino can do or cant do it)?
sw or hw ???
sw or hw ???
Sorry for late reply.
Yes, i mean flow control.When i wrote that the “full modem uart”, i wasnt realy know what is that mean.
So here is what i want to do:
I have a modem (gsm modem-terminal) software. Which it is communicating via full modem. Meaning by that, Rx, Tx, Rts, Cts. I am not shure (for now) if it has ring pin and/or other pins
My bluepill board, will plug to the usb, and its creates virtiual com port and it should handle flow control.So its need to be software.Right?
After that. I have hardware uart which talk with real gsm gprs module (it has full modem pin.I belive 8 pins). I know that i can handle this with uart2 or uart3 on stm32f103c8. Cant be uart 1 beacuse of usb pins.
Did I express myself expressly? If i did, how can i do this?
We have already a thread regarding GSM modules: http://www.stm32duino.com/viewtopic.php?f=45&t=1079
In the mean time, i will learn much more info about my module.
Thanks
