I was writing the below a few minutes ago
Ilija, I tried something and I see that your request can be managed with
CDL property 'make' and external Tcl script to generate some kind of
io_serial_tty.inl on a fly like eCos 'heapgen.tcl' generates that
heap.hxx, but I have a doubt about such a "complexity". By other hand
the original tty and termios config files won't to have a mess with
complex scripting as all details can be hidden in the external Tcl
script. Eternal dilemma: Universality vs. Simplicity. I would prefer S.
here (c & p), but, this is my view only.
I think that you have to create bugzilla report is describing your issue
(=request) without a solution and then we will discuss the ways to
resolve the issue and I hope you will have more hands for that.
Thank you,
Sergei
