Chapter 7 - Commands and Messages

DISCONNECT in progress

A disconnect has already been issued. Connects are not legal in this state and a second discon-

nect will cause a "retry count exceeded" condition.

REJ frame sent

A reject packet has been sent in response to a packet received out of proper sequence.

Waiting acknowledgment

The time specified by

FRack

has been exceeded without a proper acknowledgment for a packet

sent. A retry sequence is in progress.

Device busy

The KAM is not able to accept further data packets from the radio for the time being. An RNR

(Receiver Not Ready) has been sent.

*** FRMR sent

Frame reject packet has been sent due to a detected error in protocol. Three bytes (6 hexadec-

imal characters) are displayed to assist in determining the reason for the reject.

*** FRMR received

A frame reject packet has been received for an unknown reason. The information field of this

packet will display in hexadecimal value. This display may be useful in determining why the receiv-
ing station rejected your packet.

PBBS NOT ENABLED

This is the KAM response to a

PBList

PBRead

PBKill

PBSend

command if the PBBS has not

been enabled by allocation of RAM.

PBBS BUSY

This is the KAM response to a connect request when it is already connected to.
