; USED WHEN THE LINE IS GOING MO%RMT.
; (2) IN THE OTHER CASES, IF MO%AUT=0 THEN SET TTSPWD ONLY IF THERE IS
; A DYNAMIC DATA BLOCK. THIS COVERS THE CASE OF PRESERVING LINE
; SPEED WHEN A LINE IS REMOTE ONLY AND LEAVING SPEED ALONE IF
; A LINE IS AUTOSPEED AND NO DYNAMIC DATA EXISTS. WE SET THE SPEED
; IN THE FRONT-END IN THE REMOTE CASE.

Cause: A terminal line on RSX20F is generating input at an excessive
rate. It is being shut off for 3 seconds by having its input
speed set to 0. This can result from a noisy line which has a high
input baud rate. If an EIA line, it may be too long and so picks
up electrical noise.
Action: This problem can be prevented by eliminating the noise or reducing
the input speed.
