Describe the bug
The system does not see the GPS module GT-U7 Satellite Navigation Module 10M
The port, pin, and speed settings are correct, so messages are exchanged on the RX PIN 44 TX pin 43 Baud 9600 settings. If you set other settings, you will not receive messages.
I checked the operation of this GPS module on other firmware (mesh os, ripple), it works successfully on them, which means that the problem is in the firmware.
During the tests, I see the GPS module working, when it sees satellites, it blinks the LED.
Also I can`t see my location on MAP.

Which device are you using
LilyGO T-Deck

Which Firmware are you using
v. 0.9.12

To Reproduce
Steps to reproduce the behavior:
