BUG.(INF,TTYSTP,RSXSRV,HARD,<Line has been shut off because of excessive input rate>,<<T2,LINE>>,<
Cause: A terminal line on RSX20F console front end is generating input at an
excessive rate. It is being shut off for 5 seconds by having its input
speed set to zero. The high input rate can result from a noisy
terminal line which has a high input baud rate. If an EIA line, it may
be too long and so picks up electrical noise.
Action: The terminal line number specified in the additional data should be
checked. This problem can usually prevented by eliminating the noise
or reducing the input speed. If all connections to the terminal line
are tight and the line speed has not been changed recently, the front
end hardware should be checked by Field Service.
