Hi All,

Has anyone ever experienced a 'lock out' condition when uploading from an S5-135U system with 928B CPU using the comms port?

I had an intermittent connection problem which was the same using various combinations of TTY interface and Laptop or PG.

This became 'permanent' after a couple of hours, but was apparently 'reset' by site after complete reboot and reload of software. I didn't witness the reboot/reload and suspect site changed the CPU card to a spare and that the problem was really a dry-joint or similar on the D-type connector for the comms port.

Many thanks in advance...
