# OpenLRS

## Details

**Protocol Number:**  27

## Notes

This is a reservation for OpenLRSng which is using the MULTI-Module's serial protocol for their modules.  See <https://openlrsng.org/> for more information.&#x20;

There is no MULTI-Module protocol associated with protocol number 27, so it is ignored.
