|
|
This option enables telnet as a network console service. It is for
|
|
now a very basic implementation of the telnet protocol. Currently,
|
|
it is basically just a redirection of the Zephyr console through TCP.
|
|
It nicely works along with another console driver (like uart), twist
|
|
being that it will take over the output if only a successful
|
|
connection to its port is done.

int "Telnet console line buffer size"

default 64
|
|
help
|
|
This option can be used to modify the size of the buffer storing
|
|
console output line, prior to sending it through the network.
|
|
Of course an output line can be longer than such size, it just
|
|
means sending it will start as soon as it reaches this size.
|
|
It really depends on what type of output is expected.
|
|
A lot of short lines: better reduce this value. On the contrary,
|
|
raise it.

help
|
|
This option can be used to modify the amount of line buffers the
|
|
driver can use. It really depends on how much output is meant to be
|
|
sent, depending on the system load etc. You can play on both
|
|
TELNET_CONSOLE_LINE_BUF_SIZE and this current option to get the
|
|
best possible buffer settings you need.

This option can be used to modify the minimal amount of a line buffer
|

that can be sent by the telnet server when nothing has happened for
|
|
a little while (see TELNET_CONSOLE_SEND_TIMEOUT) and when the line
|
|
buffer did not meet the line feed yet.

Current support is so limited it's not interesting to enable it.
|
|
However, if proven to be needed at some point, it will be possible
|
|
to extend such support.

For telnet developers only, this will forward each output to
|
|
original console handler. So if by chance telnet seems silent,
|
|
at least things will be printed to original handler, usually
|
|
UART console.
