But today we will analyze other options that we can use as a terminal. Being much more configurable and with more suitable environments for a management task. Continue reading for more information. Best Terminal for windowsNow let’s check the best terminals which we are to provide below. These are the popular terminal for windows 10, 8, and 7 to edit any code easily. Check them right away 1) ZOCZOC has been developed as a professional ssh client and terminal emulator for Windows environments.
It has a large list of emulations and features, which makes it one of the best tools for tasks such as connecting to hosts and mainframes using a secure shell, telnet, and other communication methods available. It has a current interface in which the tasks to be executed will be much simpler. It can work with msysgit, PowerShell, Cygwin, and mintty, which allows us to take full advantage of all Unix capabilities in Windows.

I need help with how to change how Windows 7 controls a serial COM1 port default settings. I use a very simple serial cable to control special external hardware with. The serial cable only uses the RTS, DTR and GND pins of the cable and does not requireany special hardware drivers.
Serial Terminal Windows 7 64 Bit
I have used the device on several prior versions of Windows 95 through XP with no issues at all with the serial ports. With Windows 95-XP the serial COM1 port had RTS and DTR lines set 'off' by default. I just upgraded to anew computer with Windows 7 and now having an issue with the serial port.For my issue, I need to have the serial port be 'off' by default until the control software loads and specifically opens the serial port to turn the external device 'on'. Using a serial port data tester (has lots of green and red led's) I can see that assoon as Windows 7 boots up, it automatically sets the serial port DTR, RTS and TD lines as 'HOT' (high voltage). This is not acceptable as it activates the external hardware before the control software is loaded! Likewise when the control software is closedand the serial port is released back to Windows 7, the serial port DTR, RTS and TD lines are again set as 'HOT' (high voltage) by Windows.Computer: Dell Optiplex 745Windows 7 Pro 64 bit with SP1 installedSerial Port on motherboard: Intel ICH8/ICH8R LPC Interface Controller 2810Serial Driver: Microsoft 6.1.7600.16385 (is up to date)Settings for COM1:-Baud Rate: 9600Data Bits: 8Parity: NoneStop Bits: 1Flow Control: NoneI have spent hours looking at Device Manager/port settings and trying to find anything online with no luck.
Is it possible that this is due to how Windows 7 plug-n-play handles the serial port? How can I disable this so the port is 'off' by default like itwas on XP and earlier versions of Windows?Thanks, Dave.

I was having the same problem as you when trying to control my radio interface. I just switched to a Dell Optiplex over the weekend and noticed the same problem.
I was searching theweb for an answer when I found this post. I am happy to say that I found the fix for my Optiplex and how it works for you. I went into the BIOS and set the UART protection to On. Doesn't make any sense to me because I'm a software guy, only an amateur onthe hardware side. I exited the BIOS and serial port is working as it should just like under XP.
