![]() ![]() ![]() In that case, the command string should be - String command = "xterm"ĭo look at the comment, because it also points out the problem with using find. I think the best way is to let the user configure the whole thing.Ģ.I got a comment on this answer (by ypnos), suggesting that I avoid using absolute paths and rather rely on the command being in the PATH environment variable. As others have already pointed out, xterm (or any other terminal of your choice) may not be in the path specified (/usr/bin/.) and may not even be installed, so you might have to use some fancy command string (Ex: pipelining find through grep to get the path to xterm before launching), which isn't such a great idea. A better solution is to accept command line arguments for the users preferred shell or to use a configuration file which the user can change to make your script open the shell of his/her choice.ġ. I suggest you catch an exception in case the terminal you chose isn't present and handle it by asking the user to install it. The command string can also be modified to use different shells like zsh. The serial port provides the physical connection between the equipment but a communication protocol has to used to ensure a reliable, error-free data path. How can I do that How do I know whats the port where I've plugged the serial jack into and how to access it I need some terminal emulator kind of thing. I need to connect to the console port of switch via serial port on my computer. You might want to open another terminal emulator like rxvt, eterm, aterm, gnome-terminal or konsole. A serial port connection can be used for inter-processor communication within a system or for communication with different parts of a system. My computer and switch both are connected to network. tty device that you may come accross are serial devices, for example a serial port. The basic assumption I have made is that you want to open xterm, which is available on almost any system (with X installed of course). There are other terminal emulators which you can use such as xterm. Public static void main(String args) throws IOException This helps to identify each device connected. COM Port (Serial Port) - Each device you connect to your computer will be assigned a specific port number. ![]() This should be hooked up to the TX line of the device with which you would like to communicate. To open a terminal window, you just have to modify your command string like this:- import java.io.* The RX line on any device is there to receive data. A terminal emulator provides an interface (window) for the shell and some other facilities for using the command prompt. Each shell is basically a command interpreter that understands Linux commands (GNU & Unix commands is more correct I suppose.). We dont care about the output of termix-usb-l we only care about new /dev/tty devices. From one end, open /dev/ptyp5, and then attach your program to /dev/ttyp5 ttyp5 will act just like a serial port, but will send/receive everything it does via /dev/ptyp5. ![]() When I connect the cable and enter termux-usb-l in Termux, the output says '/dev/bus/usb/001/002'. You can use a pty ('pseudo-teletype', where a serial port is a 'real teletype') for this. dev/ttyUSB0 then you will NOT be able to use it as a serial port with Node-RED. Similarly, when I'm unable to ssh to the server, I want to be able to connect somehow remotely when I can't ssh remotely or locally.Īppreciate your input on these two things.In Linux, there are a number of terminal emulators which allow you to interact with various shells. If you dont get a new entry under /dev e.g. Many times I'm unable to connect to the Ubuntu servers due to VFS limit reached so only option is to reboot and when you have server years old then it's scary to reboot so I was wondering if there is still a way to connect to it and increase the limit by somehow connecting to it to prevent the reboot. This will help you to save lots of time when you have to logon to 20-50 terminals a day so I'm a fan of this feature however I also use my Windows machine but I have not been able to find such an option on a windows environment.So.if you're aware of any terminal that might help then please let me know.Ģ. I have been trying to figure out two situations and I hope you can provide some valuable input.ġ on a Mac you can use iterm2 which enables you to send text using a keystroke which has the password saved when you configured it. Linux newcomers can install GTKTerm, a graphical serial terminal emulator for Linux. ![]()
