Select the correct COM port and click Rename. So far, this is the only program that meets my requirements. Left click on Show Hidden Icons and then right click on the Serial Port Notifier icon. Yeah, my vision is not as good as it used to be and I really would like to be able to change that font a bit. In the real application, I might want to control that. I have a wire loopback on the RS-232 connector and if I send a file with three commands, terminated with CR/LF, it displays all of that, before displaying any of the received data. It also seems to block data, before display. They distinguish Tx from Rx by colors of underline. It lets me adjust the font size in the data display, but not the font or other features, like bold. I've looked at Hterm a bit now and it seems to have all the features I need. If it displays the control characters, allows sending a file without a protocol, and highlights send and receive differently, that's my boy! Zoc does not fit that bill at all. The correct driver should install automatically for Windows 10. The mini version is around 10 MB in size.

It is a portable software, which is available in 2 different versions: mini and full. A terminal emulator to me, is just that, an emulation of a terminal, such as a VT100 or a Lear Sigler. Cmder is a free, open-source terminal emulator for Windows.

This is where the communications failure occurs. Since every command ends with a CR/LF pair, it naturally displays on alternate lines. The existing app sends all comms to a telnet app, along with ANSI controls to set the bold feature for one direction and not for the other. Heck, maybe I'm better off developing my own. So the need for a way to directly interact with the com ports. I'm really trying to test the comms interface, which will have speed issues unless I can optimize the interface. In this case, I have a dumb device (that I'm designing) to receive commands, and provide replies. There are a few USB hubs that let you control power to the USB ports, but very few. Termite is an easy to use and easy to configure RS232 terminal. But once I found the right tool, it worked well, other than not being able to reset the target since the com port was USB. The trick in that case was handling all the details of control characters, as to which were intercepted by whom. I don't recall the setup I ended up with, but I had to run something on the PC to log into the rPi, (maybe Putty), then a different program on the rPi to connect to the target via the comm port. Trying to find a terminal emulator for Linux is nearly impossible, because they consider the command line to be a terminal emulator! lol I had a different setup, where I was using something like SSH to log into an rPi which was connected via a serial port to an embedded target. One problem I have is that the term 'terminal' seems to also be used for command line interfaces. Otherwise, it is a simple terminal application. I just want it to show the transmitted and received data in different colors, or brightness or backgrounds. Using a terminal program, you can send low-level commands through a serial port or through a network connection. I need a terminal interface to a COM port.
