# Ports

![Workstation Options - Ports](https://documentation.payfacto.com/POS/MaitreD/Fulldoc/assets/images/Chap05/WorkstationOptions/06-WSOptions-Ports.png)

The Ports branch of the workstation options allows you to remap Maitre'D ports to custom Windows COM ports.

### Windows Port Mapping

#### Port #1 through Port #4

For each Maitre'D port, select the Windows COM port number to use.

This is especially useful in situations where Windows assigns the lower COM port numbers to internal system hardware, and the actual available COM ports are COM 5 through COM 8, for example.

Also, some USB-to-Serial adapter drivers will set the emulated COM port number to COM 9 or higher. This is another situation where port remapping would be required.
