What is HTerm?
HTerm is a serial communication terminal for Windows. It connects to hardware serial ports and virtual USB serial ports, letting you enter and inspect data in ASCII, hexadecimal, decimal and binary. It is useful when you need to examine the bytes exchanged with a serial device rather than work only with readable text.
Port settings include baud rate, parity and flow control. HTerm can send and receive files, and its XML configuration files let you retain customized settings. The publisher README also documents commands for changing DTR and RTS signals and inserting a wait into an input sequence.
A custom baud rate only works if the port hardware supports it; unsupported values produce an error. The publisher also documents a Windows startup error involving VCRUNTIME140_1.dll and points to the Microsoft Visual C++ x86 runtime. The linked Windows download is the publisher's ZIP package.
The screenshot is an older Windows interface illustration supplied by the publisher, visibly titled HTerm 0.6beta, not a capture of version 0.8.9. The current product page lists 0.8.9. The publisher permits commercial use but forbids selling or modifying the program and requires written permission for redistribution; this entry links to the publisher-hosted package rather than mirroring it.
