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. A terminal emulator to me, is just that, an emulation of a terminal, such as a VT100 or a Lear Sigler. 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. 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. Trying to find a terminal emulator for Linux is nearly impossible, because they consider the command line to be a terminal emulator! lol 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. 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. I need a terminal interface to a COM port. The product's various editions also include features for sending Modbus protocol commands (ASCII/RTU Modbus requests/responses) and creating automated test tasks both from the UI and with the help of Serial Port Terminal API (supports JavaScript/TypeScript).Not sure I understand that. It also allows you to control auxiliary modem and handshaking lines (CTS, DSR, RI and CD), toggle RTS/DTR lines. It supports all standard/non-standard Baud rates, Data bits, Stop bits, Parity (odd/even/mark/space), software XON/XOFF and hardware flow control. It supports sending/receiving sequences of binary, hex, decimal, octal, float and double data as well as sending characters in virtually any encoding including ANSI, EBCDIC, ISO, OEM, ISCII, MAC, multi-byte UNICODE UTF-8, UTF-16 over a serial line. It supports RS-232, RS-422, RS-485 legacy or PnP serial ports, software-based virtual serial ports, and all kinds of USB COM ports created by USB to serial adapters or USB-to-RS232 converter cables.īasic functionality includes sending bytes, text characters, non-ANSI/ASCII characters and files over a serial transmit line. You will find this Terminal extremely useful if you need to create automatic tests or simulate behavior of serial software applications and physical serial devices. It allows both communication with modems, routers, GPS receivers/transmitters and debugging of communication protocols for sensors, robots, complex automated lines and other industrial equipment. This program facilitates the development and debugging, reverse engineering, testing/analysis of serial applications and hardware devices that use RS232/RS422/RS485 serial interfaces. HHD Software Automated Serial Terminal is a software utility that allows you to send/receive data via COM ports in various formats and to automate communications using scripts. Serial port communications automation & simulation tool for hardware & software developers
