| menuconfig TELNET_CONSOLE |
| bool "Enable a super basic telnet console service" |
| default n |
| select NETWORKING |
| select NET_TCP |
| help |
| 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 anothe console driver (like uart), twist |
| being that it will take over the output if only a successul |
| connection to its port is done. |

| config TELNET_CONSOLE_PORT |
| int "Telnet console port number" |
| default 23 |
| help |
| This option is used to configure on which port telnet is going |
| to be bound. |
| |
| config TELNET_CONSOLE_LINE_BUF_SIZE |
| 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. |
| |
| config TELNET_CONSOLE_LINE_BUF_NUMBERS |
| int "Telnet console line buffers" |
| default 4 |
| 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. |
| |
| config TELNET_CONSOLE_SEND_TIMEOUT |
| int "Telnet console line send timeout" |
| default 100 |
| help |
| This option can be used to modify the duration of the timer that kick |
| in when a line buffer is not empty but did not yet meet the line feed. |
| |
| config TELNET_CONSOLE_SEND_THRESHOLD |
| int "Telnet console line send threshold" |
| default 5 |
| help |
| 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. |
| |
| config TELNET_CONSOLE_SUPPORT_COMMAND |
| bool "Add support for telnet commands (IAC) [Experimental]" |
| default n |
| help |
| 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. |
| |
| config TELNET_CONSOLE_THREAD_STACK |
| int "Telnet console inner thread stack size" |
| default 1024 |
| help |
| This option helps to fine-tune telnet's inner thread stack size. |
| |
| config TELNET_CONSOLE_PRIO |
| int "Telnet console inner thread priority" |
| default 7 |
| help |
| This option helps to fine-tune telnet's inner thread priority. |
| |
| config SYS_LOG_TELNET_CONSOLE_LEVEL |
| int "Telnet console log level" |
| default 0 |
| help |
| Sets log level for telnet console (for telnet console dev only) |
| |
| Levels are: |
| |
| - 0 OFF, do not write |
| |
| - 1 ERROR, only write SYS_LOG_ERR |
| |
| - 2 WARNING, write SYS_LOG_WRN in adition to previous level |
| |
| - 3 INFO, write SYS_LOG_INF in adition to previous levels |
| |
| - 4 DEBUG, write SYS_LOG_DBG in adition to previous levels |
| |
| config TELNET_CONSOLE_DEBUG_DEEP |
| bool "Forward output to original console handler" |
| depends on UART_CONSOLE |
| default n |
| help |
| For telnet developpers 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. |
| |
| config TELNET_CONSOLE_INIT_PRIORITY |
| int "Telnet console init priority" |
| default 99 |
| help |
| Telnet console driver initialization priority. Note that Telnet works |
| on application level. Usually, you won't have to tweak this. |
