IDK about MacOS, but on Windows 9x/XP, sending bytes via serial was incredibly trivial in C#, Visual C++ or even ols school Visual Basic.[1]
Even if you didn't have one of the dozens of already written serial terminal apps, you could write your own pretty easily in one of those languages to push bytes out the serial port, with just a few standard API calls.
I doubt MacOS didn't have something similar. Unless of course, MacOS back then was somehow shittier than Windows, which I doubt.
