Ivan Bernatović Are we talking about two RADICALLY different programs when it comes to Hyperterminal or something? There is NO shell attached to it, bash, command prompt, or otherwise... it can CONNECT via telnet/ssh (or even just conventional serial) to a service providing BASH, or the command shell, or power shell, but that has dick-all to do with what it has "out of box"
Also, when did it become and Electron app?!? I'm pretty sure it isn't since it has existed for some two DECADES before Atom was a twinkle in Chris Wanstrath's eye... and by all appearances its codebase has remain untouched and unchanged since the XP days. Lands sake I ran HyperAccess (the full version of Hyperterminal) on my Heathkit H-161 off floppies. You might as have included Procomm or Kermit. ... no? How about Crosstalk?
I was really shocked to even find someone mentioning it... Particularly given the ridiculous price. (Since the free demo is time locked shareware and M$ stopped bundling the dumbed down version with Windows -- hence why I suggest Putty.)
Or are you referring to something ENTIRELY different? Because what you describe and how you're talking about it has dick-all to do with what HyperTerminal is, what it does, or what it's for! Hell, I don't even think it can actually connect to windows itself for shell access... at least, not the versions they bundled with decade out of date copies of Windows. Likewise as a NATIVE app it should be faster, though it's so old it's not using the modern Windows API and is instead using unaccelerated calls dating back to windows 3.x level compatibility... and the wrappers for the old GDI calls often drag such programs performance down so badly on modern systems they behave worse than they did on 486's. It's a relic of the pre-internet dial-up days that hasn't even seen a real code update since that time!
On the whole (and yes I re-read) what you're saying is a bunch of stuff that where I'm from would just make Windows development HARDER. Ridiculously overthinking the simple with tools you don't need.
Though to be fair, I say that about things like NPM, frameworks, and a whole host of other things that are 'hot and trendy' right now -- guess it's a matter of perspective.
