Probable Cause and Solution
The terminal emulation program interline and intercharacter delays
are not set to zero. If the load was successful, no further action is
necessary. If the load was terminated prematurely, reset the interline
and intercharacter delays to zero, and reload the software.
The terminal has not been reset to 9600 baud. Reset the terminal
any time after loading the new software. After changing the
terminal baud rate, press Return to display the prompt (>).
