2.2.5 MDM.receivebyte(timeout)
This command receives a byte from AT command interface waiting for it until timeout is expired.
Request to Send (RTS) is set to ON. Input parameter timeout is a Python integer which is measured in

b.
2.2.6 MDM.readbyte()
This command receives a byte from AT command interface without waiting for it. Request to Send
