Fix the following UCLID5 code using the compiler feedback provided below.

```

include "integers.ucl5"

    module c_d_channel {
        input c: bool
        output d: bool
    }

    module sender {
        const TIMEOUT_LIMIT: int

        input S: bool
        input m: int
        input b: bool
        output c: bool

        var timeout_counter: int = 0

        assume TIMEOUT_LIMIT > 0

        init {
            assert timeout_counter < TIMEOUT_LIMIT
        }

        transition {
            if S == true && c == false {
                c' = true
            } else {
                c' = c
            }
        }

        transition {
            if c == true && d == true && b == true {
                timeout_counter' = 0
            } else {
                timeout_counter' = timeout_counter + 1
            }
        }
    }

    module receiver {
        input c: bool
        input d: bool
        input b: bool
        output R: bool

        init {
            R = false
        }

        transition {
            if c == true && d == true {
                R = !b
            }
        }
    }
```

Reply with your UCLID5 code inside one unique code block.

I can definitely do that! Here is the UCLID5 code:
