https://github.com/ezramorris/PyVirtualSerialPorts is a good example it seams (for creating fake usb location) then just symlink from pty to specified path

Looks like pyserial plus reimplemented usb CDC parser would be fine, then just open a pty in python for that

Usb tty usage on unrooted
Just did; I just dont think thats how I will implement it, they seam to not actualy lie, termux dose that. Termux api just send a fd that termux can then access in that subprocess (being inherited from the upper process that calls to the termux api after termux api uses 
outputSocket.setFileDescriptorsForSend(fds);
outputSocket.setFileDescriptorsForSend(fds);
in 
sendFd(PrintWriter out, int fd) {
sendFd(PrintWriter out, int fd) {
)

Yeah looks like I may do this in python later then; it looks possiable on termuxapi with the returned fd from a api call; but most likely more versitial to do it this way

I understand; just asking how you would suggest I do this if I ever get there, also so I can deside how to implement it (language, and if its compiled or not)

Usb tty usage on unrooted
Should I fully implement it there, and just put a request in at the packaging system? I have never made a project like this before, nor really worked on termux, so honestly asking

Usb tty usage on unrooted
You mean the /dev/? For almost all programs this is just the default place, but not required. I am kinda asking the same thing; should this be just a userspace package, I can make it easily in python based on a few projects?

Also, should we do this inside termuxapi, or should this just be a userprogram? beacuse it currently would work as a package requiring the usb forward function in termux api

Usb tty usage on unrooted
Last question because I am not really in on how termux dose some stuff; is there any overlay fs in /dev/ or are they just raw android /dev? If it has a overaly fs it should be easy, if not, I need to do it in a diffrent folder, prob specified by a argument

I just mean a pty genearted by termux and as in faking it being a usbtty; sorry if I was not clear https://man7.org/linux/man-pages/man7/pty.7.html I mean socat can make one, and that works for almost any program, so I would assume that works https://unix.stackexchange.com/questions/493572/create-pty-and-connect-it-to-a-serial-port-dev-ttyusb0

Usb tty usage on unrooted
can we just add a fake fifo / pty object there, or do we really need LD_PRELOAD? I mean I can write a proxy for open and read.... but is there no day?

Usb tty usage on unrooted
Will see if I have time; do we know if we can just include https://github.com/mik3y/usb-serial-for-android/tree/master as MIT code into termux or should I rewrite it? If I rewrite, can I use the MIT code (with credit) to the author in termux api? Its GPL v3 so it should be applicable
