Micro python modem connection help

[emigbur]

Hi
I did a small script to comunicate whit modem using micropython but im not able to get response.
If some one can share a script example to use?

Thanks

This is my simple try

`from machine import Pin, PWM
from time import sleep
from machine import UART
from Modem import Modem
import time

pin1 = Pin(4, Pin.OUT)
pin2 = Pin(12, Pin.OUT)

modem = Modem(pin1, pin2)

modem.on()

time.sleep(1)
uart = UART(1, rx=27, tx=26, baudrate=115200)
uart.init(115200,bits=8,parity=None,stop=1)
uart.write('AT\r\n')
print(uart.read())
print(uart.read())
print(uart.read())
print(uart.read())

modem.off()`
