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
