68 Rocket Model 204 Terminal User’s Guide
Invoking and disconnecting from the CMS terminal interface
these terminals in Chapter 3 does not necessarily apply when teletypes are
used.
Selection of terminal support mode
Two modes of CMS terminal support are available to Model 204 users:
multiuser and single-user. To select multiuser mode, the system manager must
set the IODEV parameter on the user’s parameter line for the terminal. To
select single-user mode, the system manager must set the ALTIODEV
parameter in the single-user EXEC.
For more information about these system manager actions, see the Model 204
CMS Installation Guide for your operating system and the Model 204 System
Manager’s Guide.
Invoking and disconnecting from the CMS terminal interface
The steps required for logging in to Model 204 through the CMS terminal
interface and for disconnecting from the CMS terminal interface are described
in this section.
Getting online
To connect to Model 204 through CMS, follow these steps:
1. Gain access to CMS by following the z/VM connect procedures defined at
the installation. Check with the system manager for specific information.
CMS indicates that it has gained control by displaying a ready message.
2. Connect to Model 204 by using the M204 EXEC (described in “M204
EXEC”), which formats the Model 204 command. The M204 EXEC estab-
lishes the environment in which to run Model 204. Refer to the Model 204
System Manager’s Guide for more information on the M204 EXEC. After
this command has been accepted, a prompt is displayed. On the 3270, for
example, a greater than sign (>) is displayed.
3. Log in to Model 204 in the usual way, if not already logged in by a com-
mand file in the M204 EXEC (see the CMD option in the section “M204
EXEC options” on page 69).
M204 EXEC
The format of the M204 EXEC, as distributed by Rocket Software, is shown
below. If an option is not specified, Model 204 provides a default. Defaults can
be established for an installation by the system manager, as described in the
Model 204 System Manager’s Guide. The user can obtain more information
about the M204 EXEC by issuing the HELP 204 M204 command.
