Чтение из последовательного порта с помощью языка C в visual studio

---

привет, ребята. Я делаю некоторый com - порт ввода-вывода в C с помощью visual studio. Я успешно написал запрос в порт. Теперь проблема заключается в том, чтобы прочитать то, что было отправлено. Он получает данные, но это просто жаргон, вероятно, мои типы данных. может кто-нибудь, пожалуйста, помочь с этим. мой код здесь

#include <stdio.h>
#include <conio.h>

Что я уже пробовал:

Я попытался изменить свои типы данных, так как то, что возвращается, - это вопросительные знаки, когда я использую char и только 6363(все время), когда я использую int
