keyword=Hadron dipole ps - comm failure
During the change to new P0 = 2.796 from 3.028, hadron dipole power supply
failed to respond. Problem was traced to serial communication card which behaved
like the communication buffers were full. A soft reset (by login into the IOC and
performing a reboot or ctrl-X) was performed but it did not clear the problem.
A hard reset was then performed (green button - middle room). Problem cleared.
Problem must have been due to an internal register of the serial communication
card being stuck.
