Be sure to call via axport name defined into axports file first parameter. However, for your information, on two PC of different generation boards (Pentium II CPUs) I have been using successfully for years two 2 ports KPC9612 in kiss mode with kernel 2.2. But I have never been able to run AX25 correctly with any 2.4 kernels. I always experienced interrupts problems and kernel oops and finally Linux halted. And one of the symptoms was that Call did not work ! The good news is that I recently tried kernel 2.6.0 and that AX25 is working back again for me (listen and call working fine). I used Mandrake Linux 10.0 RC1 Cooker distro for this purpose. Of course I had to adjust some kiss parameters as serial devices have been renamed (i.e. ttyS1 ---> tts/1). For example : /usr/local/sbin/mkiss /dev/tts/1 /dev/pty/m3 /dev/pty/m4 /usr/local/sbin/kissattach -i 44.151.75.15 -m 256 /dev/pty/s3 0 /usr/local/sbin/kissattach -i 44.151.75.15 -m 256 /dev/pty/s4 1 with 0 and 1 bounding ax0 and ax1 respectively as defined in axports. I am now seriously thinking of upgrading my AX25 station with this new kernel which works faster (with more functionnalities than 2.2). 73 de Bernard, F6BVP
