Receive Ready is used by an endpoint to indicate that it is ready to receive an information
frame and/or acknowledge previously received frames
Receive Not Ready is used to indicate that an endpoint is not ready to receive any
information frames
REJect is used to request the retransmission of frames
Selective REJect is used by an endpoint to request retransmission of specific frames. An
SREJ shall be transmitted for each erroneous frame; each frame is treated as a separate
error. Only one SREJ shall remain outstanding on each link direction at any one time
Meaning
S-Frame
Supervisory(S) commands and responses are used to perform numbered supervisory functions such as acknowledgment, temporary
suspension of information transfer, or error recovery. Frames with the S format control field do not contain an information field
ModifierFrame Status
11001RESET Mandatory
00110UA Mandatory
Reset of data link layer is used to reset the sequence number variables in the both
endpoints
Unnumbered Acknowledgment is used to acknowledge the receipt and acceptance of a
RESET command
Meaning
U-Frame
The unnumbered format commands and responses are used to extend the number of data link control functions. The unnumbered
format frames has 5 modifier bits which allow for up to 32 additional commands and responses. Only a subset of the HDLC commands
and responses are used for SHDLC
I-Frame
The functions of the information command and response is to transfer sequentially numbered frames, each containing an information
field, which might be empty, across the data link
