[rtl] rt_fifos + Tcl/Tk

[Charles André]

Hi,   1- Tcl access to rt_fifos ----------------------------------- I remember a mail , several months ago, saying that Tcl/Tk was still a good interface from the Linux world to the RTLinux world.   I tried to use a Tk panel to read and write RT_Fifos.   Tcl says that    open /dev/rtf0 r  is illegal.   I managed to read rt_fifo using a trick:         set f0 [ open "| cat /dev/rtf0" ] this works.   But what about writing? It's always the same problem with input redirections.   I think the best solution is to write DRIVERS for Tcl, dedicated to rt_fifos. Has someone written those drivers?   Thanks in advance for any suggestions.     ------------------------ 2- Mutation ?  why device number for rt_fifos has shifted from 63 to 150 ?   --------------------------   Looking forward to reading you.   Charles   [EMAIL PROTECTED]  or   [EMAIL PROTECTED]
