Automated file transfer

Event-driven bidirectional file transfer

Automatically detect newly created files and securely transfer them between legacy DECnet environments and modern TCP/IP systems without operator intervention.

ZTLC™ continuously monitors configured folders, detects new files in real time, queues transfers, verifies successful delivery and maintains complete audit logs for every transaction.

  • Real-time event detection
  • Automatic queue management
  • Automatic bidirectional transfer
  • Transfer verification
  • Automatic retry
  • Audit logging
  • No application changes
  • Enterprise integration

Remote administration

Remote command execution

Execute VAX/VMS commands remotely from a Windows administration workstation without requiring direct console access.

ZTLC™ securely transfers command files, executes them on the target VAX/VMS system, retrieves execution results and presents them back to the administrator’s workstation.

Remote administration

Manage legacy servers from modern workstations.

Faster troubleshooting

Reduce maintenance and support time.
