END-class command failed.
Packets sent: 1301
Retransmissions: 11
Timeouts: 0
Damaged packets: 0
Fatal Kermit Protocol Error: Too many retries
HINTS... If the preceding error message does not explain the failure:
Try changing the remote Kermit's FLOW-CONTROL setting.
Try it again with SET STREAMING OFF.
Try it again with SET PARITY SPACE.
As a last resort, give a ROBUST command and try again.
Also:
Be sure the source file has read permission.
Be sure the target directory has write permission.
(Use SET HINTS OFF to suppress hints.)
