? ????bf???l????????b@b????d@c? 是什么东西?
谢谢!
请大佬帮忙分析一下,怎么理解以下的内容。
<pre>Command Function Comments
0 Data frame The rest of the frame is data to
be sent on the HDLC channel.
1 TXDELAY The next byte is the transmitter
keyup delay in 10 ms units.
The default start-up value is 50
(i.e., 500 ms).
2 P The next byte is the persistence
parameter, p, scaled to the range
0 - 255 with the following
formula:
P = p * 256 - 1
The default value is P = 63
(i.e., p = 0.25).
3 SlotTime The next byte is the slot interval
in 10 ms units.
The default is 10 (i.e., 100ms).
4 TXtail The next byte is the time to hold
up the TX after the FCS has been
sent, in 10 ms units. This command
is obsolete, and is included here
only for compatibility with some
existing implementations.
5 FullDuplex The next byte is 0 for half duplex,
nonzero for full duplex.
The default is 0
(i.e., half duplex).
6 SetHardware Specific for each TNC. In the
TNC-1, this command sets the
modem speed. Other implementations
may use this function for other
hardware-specific functions.
FF Return Exit KISS and return control to a
higher-level program. This is useful
only when KISS is incorporated
into the TNC along with other
applications.
</pre>
<p>The following types are defined in frames to the host: </p>
<pre>Type Function Comments
0 Data frame Rest of frame is data from
the HDLC channel.
</pre>
<p>
No other types are defined; in particular, there is no provision for
acknowledging data or command frames sent to the TNC. KISS implementations must
ignore any unsupported command types. All KISS implementations must implement
commands 0,1,2,3 and 5; the others are optional.
</p>
