The second registered port for ListCREATOR, a Japanese business-forms and report output product.
IANA registers 3914 as listcrt-port-2, "ListCREATOR Port 2", alongside 3913 for the first port, both to the same private assignee. ListCREATOR is Japanese-market software for designing and generating business forms and printed reports; the registered ports carry traffic between its client tooling and its output server. No English-language protocol documentation is public. It is essentially confined to enterprise deployments in Japan.
Do not expose
An internal document-generation service with no public security documentation; keep it on the LAN alongside the print infrastructure it feeds.
