38 Rocket Model 204 Terminal User’s Guide
IBM 3270 terminals (IODEV = 7)
Logging out and disconnecting
To disconnect from Model 204, the user logs out (if the LOGOFF procedure is
required at the installation) by entering either:
LOGOUT
or:
LOGOFF
The user can then disconnect completely from the system, reconnect to
Model 204, or connect to a different application by following the specific
procedures defined at the installation.
Screen-formatting parameters
The parameters listed in Table 3-1 apply to IBM 3270 terminals being used
through SNA Communications Server. The HDRCTL and PGSEP parameters
are not listed; they are not used with IBM 3270 terminals
The values of the first five parameters, which determine the size of the screen,
are established by the value of the MODEL parameter, which corresponds to
the terminal model within the 3270 family. Model 204 automatically sets
MODEL to the appropriate value for SNA Communications Server 3270s, but
the user also can reset it.
Terminal model options
Table 3-2 shows the valid settings for MODEL, the corresponding 3270 terminal
types, and the corresponding default values for the screen size parameters.
The user can reset INCCC and OUTCCC to override the default values
