Host Command Summary

This appendix lists the host commands that are valid in each terminal emulation mode. Additional special commands are listed at the back.

The following conventions are used in this command list. Spaces in a command are for clarity only and are not to be entered as part of the command. A space character that is part of the command will be shown as SP. An asterisk (*) in a command indicates the location of one or more parameters except otherwise indicated next to the command.

Note that IBM 3270 and IBM 5250 emulation commands are not included because of their complexity. Refer to the manuals supplied with these terminals for the host commands that are supported.
