SIM800C send sms - Uiflow or Micropython

[Jacek]

Hi,
I'm stuck with code to send SMS, I'm not able to find how to send char at the end of command Ascii(26).
The uart.writechar is not recognized.
Code:
uart2.write('AT+CMGS="+48xxxxxxxx"\r')
uart2.write('Test SIM800') <- and here should be send ASCII(26)
wait(1)

Solution:
isMessage = (str('Test SIM800') + chr(26))
