Open Protocol spec defines rev 6 with these new fields:

• sequenceNumberSupport
• linkingHandlingSupport
• stationID
• stationName
• clientID

Missing Keys / Fields

The parser is missing the last three keys:

• node-open-protocol/src/mid/0002.js

  Line 72 in f514d00

  processKey(msg, buffer, "linkingHandlingSupport", 13, 2, position, cb) &&

• node-open-protocol/test/0002.spec.js

  Lines 191 to 205 in f514d00

  	payload: {
  	cellID: 1,
  	channelID: 1,
  	controllerName: "Teste Airbag",
  	supplierCode: "ABC",
  	openProtocolVersion: "AAAAAAAAAAAAAAAAAAA",
  	controllerSoftwareVersion: "BBBBBBBBBBBBBBBBBBB",
  	toolSoftwareVersion: "CCCCCCCCCCCCCCCCCCC",
  	rbuType: "AS254DFCVFDCVGTREDFGHJKL",
  	controllerSerialNumber: "123987ASD6",
  	systemType: 3,
  	systemSubtype: 2,
  	sequenceNumberSupport: 0,
  	linkingHandlingSupport: 1
  	}

Interestingly, the serializer has all the keys:

• node-open-protocol/src/mid/0002.js

  Lines 191 to 200 in f514d00

  	serializerField(msg, buf, "clientID", "number", 1, position, cb) &&
  	serializerKey(msg, buf, 16, 2, position, cb) &&
  	serializerField(msg, buf, "stationName", "string", 25, position, cb) &&
  	serializerKey(msg, buf, 15, 2, position, cb) &&
  	serializerField(msg, buf, "stationID", "string", 10, position, cb) &&
  	serializerKey(msg, buf, 14, 2, position, cb) &&
  	serializerField(msg, buf, "linkingHandlingSupport", "number", 1, position, cb) &&
  	serializerKey(msg, buf, 13, 2, position, cb) &&
  	serializerField(msg, buf, "sequenceNumberSupport", "number", 1, position, cb) &&
  	serializerKey(msg, buf, 12, 2, position, cb);

• node-open-protocol/test/0002.spec.js

  Lines 378 to 395 in f514d00

  	payload: {
  	cellID: 1,
  	channelID: 1,
  	controllerName: "Teste Airbag",
  	supplierCode: "ABC",
  	openProtocolVersion: "AAAAAAAAAAAAAAAAAAA",
  	controllerSoftwareVersion: "BBBBBBBBBBBBBBBBBBB",
  	toolSoftwareVersion: "CCCCCCCCCCCCCCCCCCC",
  	rbuType: "AS254DFCVFDCVGTREDFGHJKL",
  	controllerSerialNumber: "123987ASD6",
  	systemType: 3,
  	systemSubtype: 2,
  	sequenceNumberSupport: 0,
  	linkingHandlingSupport: 1,
  	stationID: "AESDR56RDT",
  	stationName: "QASWWEDXCVFR562 DERF34EDF",
  	clientID: 9
  	}

I would expect the parser and serializer to behave as inverses to each other.

Wrong type for stationID

Additionally, the type for stationID is also wrong. The official protocol says it's supposed to be a number, but node-open-protocol tries to interpret it as a string!
