tty

I have a container that is running the Apache service in the foreground. I would like to be able to access the container from another shell in order to "poke around" inside it and examine the files. At the moment, if I attach to the container, I am left looking at the Apache daemon and cannot run any commands. Is it possible to attach another tty to a running container? Possibly, I can take advantage of the fact that Docker is actually just wrapping around LXC containers? I have tried sudo lxc-console -n [container-id] -t [1-4] but it appears that only one tty is made available and that is the

I have written a program that comminucates serially with a USB 3g Modem. When I open the port and write the AT command AT To the modem, I get the normal "OK" response and can read it using a serial read function. In a terminal, when I write the command AT^SYSINFO I get the following response: ^SYSINFO:#,#,#,#,#,# With the #'s being numbers. However, when I attempt to write the same command serially using my program, I read only this reponse: AT^SYSINFO I try to then read another line of incoming data, but no data comes. Can anyone help me with this? There is information in the ^SYSINFO message

I want to read a single character at-a-time from the command line in PHP, however it seems as though there is some kind of input buffering from somewhere preventing this. Consider this code: #!/usr/bin/php <?php echo "input# "; while ($c = fread(STDIN, 1)) { echo "Read from STDIN: " . $c . "\ninput# "; } ?> Typing in "foo" as the input (and pressing enter), the output I am getting is: input# foo Read from STDIN: f input# Read from STDIN: o input# Read from STDIN: o input# Read from STDIN: input# The output I am expecting is: input# f input# Read from STDIN: f input# o input# Read from STDIN: o

I'm trying to send/receive data over an USB Port using FTDI , so I need to handle serial communication using C/C++. I'm working on Linux (Ubuntu). Basically, I am connected to a device which is listening for incoming commands. I need to send those commands and read device's response. Both commands and response are ASCII characters . Everything works fine using GtkTerm but, when I switch to C programming, I encounter problems. Here's my code: #include <stdio.h> // standard input / output functions #include <stdlib.h> #include <string.h> // string function definitions #include <unistd.h> // UNIX
