Hi! About the compilation problem, some informations are missing : - you linux version - are you using libc5 or glibc ? any way, you can add the following line in the <file>.c where is complain about errno : #include <errno.h> maybe then it will complains about other missing references or so. If you still have problems, I can send you the complete archive in .tar.gz For the other problem, I cannot help you because I don't use the same things as yours (please tell me what is your hardware configuration for packet radio : TNC, modem 'baycom' ..) Best 73, Jean-Luc
