Local PAD Emulation (padem)

Local PAD Emulation (padem)

The padem program provides local PAD emulation to enable a local terminal (real or emulated) to connect to a remote system over an X.25 PSN. x29server handles the connection on the remote host side. The remote system can be specified upon execution or with subsequent padem commands issued during operation (see illustration below).

The padem program operates in either command or data transfer mode. The operating mode depends on whether an X.121 address or a symbolic address is specified when padem is launched.

Command Mode

If the X.121 address or symbolic address of the remote host is not specified, padem begins execution in command mode and prompts the user for commands with X28> (the padem prompt).

In command mode, padem receives X.28 PAD commands from users. Any padem command can be entered at the prompt. Once padem establishes an SVC with a remote host, it switches to data transfer mode.
