record whether the cache had been accessed in order to invalidate
it when it was disabled. However, this is not needed because the

|
|
|
|
|
|
1999-07-07 20:19:36 +00:00
|
|
|
|
SYN The first character is always a SYN (ASCII 026, or ^V). SYN
|
|
|
|
|
may not appear anywhere else in the packet. Any time a SYN is
|
|
|
|
|
seen, a new packet should be assumed to have begun.

|
|
|
|
TYPE_LEN
|
1999-07-07 20:19:36 +00:00
|
|
|
|
This byte contains the upper five bits of the logical length
|
|
|
|
|
of the data section, plus a single bit indicating whether this
|
|
|
|
|
is a data packet or an acknowledgement. The documentation
|
|
|
|
|
indicates that this bit is 1 for a data packet, but the actual
|
|
|
|
|
board uses 1 for an acknowledgement. The value of the byte is
|
|
|
|
|
0x40 + (ack ? 0x20 : 0) + (len >> 6)
|
|
|
|
|
(we always have 0 <= len < 1024). Acknowledgement packets do
|
|
|
|
|
not carry data, and must have a data length of 0.
|
1999-04-16 01:35:26 +00:00
|
|
|
|
|
|
|
|
|
LEN1 This byte contains the lower six bits of the logical length of
|
1999-07-07 20:19:36 +00:00
|
|
|
|
the data section. The value is
|
|
|
|
|
0x40 + (len & 0x3f)
|
|
|
|
|
|
|
|
|
|
SEQ This byte contains the six bit sequence number of the packet.
|
|
|
|
|
The value is
|
|
|
|
|
0x40 + seq
|
|
|
|
|
An acknowlegment packet contains the sequence number of the
|
|
|
|
|
packet being acknowledged plus 1 modulo 64. Data packets are
|
|
|
|
|
transmitted in sequence. There may only be one outstanding
|
|
|
|
|
unacknowledged data packet at a time. The sequence numbers
|
|
|
|
|
are independent in each direction. If an acknowledgement for
|
|
|
|
|
the previous packet is received (i.e., an acknowledgement with
|
|
|
|
|
the sequence number of the packet just sent) the packet just
|
|
|
|
|
sent should be retransmitted. If no acknowledgement is
|
|
|
|
|
received within a timeout period, the packet should be
|
|
|
|
|
retransmitted. This has an unfortunate failure condition on a
|
|
|
|
|
high-latency line, as a delayed acknowledgement may lead to an
|
|
|
|
|
endless series of duplicate packets.
|
|
|
|
|
|
|
|
|
|
DATA The actual data bytes follow. The following characters are
|
|
|
|
|
escaped inline with DLE (ASCII 020, or ^P):
|
|
|
|
|
SYN (026) DLE S
|
|
|
|
|
DLE (020) DLE D
|
|
|
|
|
^C (003) DLE C
|
|
|
|
|
^S (023) DLE s
|
|
|
|
|
^Q (021) DLE q
|
|
|
|
|
The additional DLE characters are not counted in the logical
|
|
|
|
|
length stored in the TYPE_LEN and LEN1 bytes.

CSUM1

|
|
|
|
|
CSUM3
|
1999-07-07 20:19:36 +00:00

|
These bytes contain an 18 bit checksum of the complete
|
|
|
|
|
contents of the packet excluding the SEQ byte and the
|
|
|
|
|
CSUM[123] bytes. The checksum is simply the twos complement
|
|
|
|
|
addition of all the bytes treated as unsigned characters. The
|
|
|
|
|
values of the checksum bytes are:
|
|
|

thing, the IDT documentation generally assumes that the remote

|

|
debugging port is not the console port. This is, however, very
