To follow up on my previous messages "uucico bug - help !", the following is
what I found from the "/tmp/uuLOG" file.

****************************************************************
notice that uucico is looping in state "30", it simply can not get out
of the "bad header" situation. The following is my "quick fix".
goto pk1.c, in routine "pkgetpack", look for the following line:-
****************************************************************************
* if (k == 9) { *
* if (h->sum + h->cntl == CHECK) { *
* pkcntl(h->cntl, pk); *
* /* Conbad = 0; this cause looping of state -awc */ *
* PKDEBUG(7, "state - %o\n", pk->p_state); *
* } *
****************************************************************************
Comment out the line "Conbad = 0;", as shown above, this will cause
uucico to give up after getting 6 bad header. This fix does not attempt
to recover from the error. It will cause uucico to exit in a ordered
manner (removing LCK..* ..etc). Does anyone know more about the finite
state machine the Pk level is implementing and can come up with a
better fix ?
thanks in advance.
