I'm looking for the actual developer of JCommUSB.
I have tried finding this application, but it appears there is no place to download it from. I have also used various search engines to locate at least a website to get in touch with the developers. The only thing found is a package hosted on a 3rd party website that provides multiple tools.
Package name: SRT/VSRT
Website: http://www.haystack.mit.edu/edu/undergrad/srt/SRT%20Software/SRT_software_exec.html
