使用TCP从COM端口读取数据

Question

I'm using a Moxa Serial Hub centralize some devices that communicate using RS-232 / NMEA protocol.

The serial hub is working as a TCP client, witch every time it receives data transmits it to a know IP/port in my machine.

The problem is that I'm not receiving the data properly (I thought all I had to do was create a TCP server that accepts connections, and read the data as bytes, but that just gives me some weird characters)

I receive the bytes...but when converting to text... its just some weird characters, I'm missing some detail in this conversion. so far I've tried:

byte[] b = new byte[1000];
int k = s.Receive(b);
Console.WriteLine(Encoding.UTF8.GetString(b, 0, 1000));
Console.WriteLine(Encoding.ASCII.GetString(b));
for (int i = 0; i < k; i++)
   Console.Write(Convert.ToChar(b[i])); 

all these 3 approaches write the same text...

Does any one know how to properly read the data in this cases?

This comment provided the solution to the problem:

So you actually get a connection request from the moxa hub and receive (wrong) data? Then it might be related to wrong serial port settings on the moxa device (probably the wrong baud rate) – Jan 2 hours ago

Indeed, the baud rate was wrong.
