More Comments on the Forthcoming Protocol

We have recently discussed NWG/RFC Nos. 36 and 39 with Steve Crocker, UCLA. Steve has asked that we elaborate on the errors, queries, and HOST status that were mentioned in NWG/RFC #39.

Please voice your opinions soon in order to affect the forthcoming protocol specifications.

ERROR MESSAGES

<ERR> <Code> <Command length> <Command in error>

<Code> is an eight-bit field that specifies the error type. The assigned codes are shown below. <Command length> is a 16-bit integer that indicates the length of the <Command in error> in bits. The <Command in error> is the spurious command.

The ranges of <Code> are shown below in hexidecimal.

00 Unspecified error types 10-0F Resource errors 10-1F Status errors 20-2F Content errors 30-3F Unused

Specific values of <Code> are shown below with their meaning.

<Code> value Semantics

00 Unspecified errors. 01 Request for an invalid resource. 02 Request for an exhausted resource, try later. 03-0F Unused. 10 Invalid <RSM>, i.e., link connected but unblocked. 11 Invalid <SPD>. 12 Invalid <ASG>, i.e., connected but no <RDY> received.
