Checkpoint markers do not appear to be sent

Issue the STAT command and check the settings for data transfer. Checkpoint information is only transferred in EBCDIC, with either block or compressed mode. The checkpoint interval must be greater than zero.

The sender of the data initiates the checkpoint information. Therefore, checkpointing must be set on at the client for a STOR, STOU, or APPE, (for the MVS™ FTP client, this is done by issuing the LOCSITE CHKPTINT=nn command with a value larger than zero) and set on at the server (by issuing the SITE CHKPTINT=nn command with a value larger than zero) for a RETR.
