backspace doesn't work correctly with termios
hi all i have problem with backspace in serial communication. this is my scenario: i have three box. box number 1 is windows system, number 2 is freeBSD8.2 and number 3 is cisco router. from box number 1 i connect to the box number 2 by putty and run a serial program on box number 2 that connects to box number 3 via a serial card. this serial program uses termios structure and manage opening, reading, writing and closing serial ports. my problem is: when i connect to box number 2 via putty, everything is okand backspace works correctly but when i run serial program and connect to the box number 3 via it, backspace do not work correctly and print ^? on screen. i searched a lot and check stty erase and erase2 options. moreover i set VERASE in termios too but nothing happened. what is the correct setting for termios to identify backspace as it should be? how can i understand what key mappings is done when i press backspace in box number 1 to erase character in the terminal of box number 3? i think some thing is wrong in termios options that causes mismatch in backspace translation. this problem has kept me busy for more than a month and i really don't know what should i do to solve it. any comments or hints are really appreciated. motlagh ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

hi all
i have a problem with backspace in serial communications. i have a
freebsd8.2 box with a serial card on it. when i connect to other freebsd
box via serial port backspace does not act as i expected. backspace shows
^? on screen. i searched alot and find out that stty has two parameters
-erase and erase2- to identify erase characters in terminal and they
should
be set correctly. i set erase and erase2 to ^? by stty erase \^? and
stty erase2 \^? commands but nothing happened.
please let me know how i can fix it. i know it is simple issue but i
really
do not know how to do that.
stty erase {press the backspace key}
Then hit the enter/return key

For those who use the laptop in transportable mode (i. e. not on the desktop as a desktop-PC substitute), those features might be interesting in order to save power. - the T61p manual details standby and hibernation modes. Is this what you refer to by suspend? Both are _different_ kinds, if I remember correctly. Standby stores machine states in RAM and buffers it with the battery power. This mode still requires power. This is ACPI states S2 and S3. Hibernate stores machine data somewhere on hard disk or SSD. This mode does not require power. This is ACPI state S4. I can go into standby with Fn+F4, or with acpiconf -s 3 but can't seem to get back. The disk starts, but the screen is corrupted, kind of black with very few white dots. That seems to indicate that the GPU memory data is lost. A typical problem with those sleep states. - I've had a quick look at acpi(4) and apm(8). APM is not in use anymore. ACPI has taken that functionality at the point in time when APM has been brought to a fully functional state.

In these states, memory contexts are held but CPU contexts are lost. The differences between S2 and S3 are in CPU re-initialization done by firmware and device re-initialization. S4: a sleep state in which contexts are saved to disk. The context will be restored upon the return to S0. This is identical to soft-off for hardware. This state can be implemented by either OS or firmware. S5: the soft-off state. All activity will stop and all contexts are lost. - Anything I should check/test in BIOS? The obvious things, but I assume the presets are already fine for a laptop. I see that power management is enabled in BIOS. Is that enough? It should be.

split-logfile
I've made the switch from apache to nginx for all the web servers I run. One thing that was missing from the nginx installs was the perl script that is used in apache-land to split a single server access file into separate files for each virtual host - split-logfile. While I could have continued to use the perl script, I decided to write similar functionality in c. The c language version uses less resources to accomplish the same task more quickly.
