I just ran ztatus and packman99 for the first time. My calc crashed after I quit packman99. When I try to send anything over to the calc I get a transmission error. I can send things from the calc to the computer fine. Now my calc froze up saying there was a transmission error, I had to take out a battery to fix that even. Cal says my (parallel) link is fine. Any ideas what is going on? Thanx, Dave
