Connected with F17, received all, disconnected turned off cabinets, moved jumper to download position. Connected via hyper terminal, hit enter, hit l, send text file, selected proper file and waited and waited. Nothing worked as stated, moved jumper back to normal, cold started and fired system up and no displays on phones and unable to connect to system. All said and done it was 9 p.m. and I had been playing with it for 5 hours, customer had to go home and I had a 1 1/2 hour drive home. Boss will meet me at 6:30 a.m. with new cabinet and hopefully customer will be back up and running by 8 a.m. with F17.
