This section explains the differences between IMF/3000 screen
sizes and SNA IMF screen sizes.
IMF/3000 |
 |
Screen size is specified either by the IBM host or in the
configuration file on the HP 3000. After Pass Thru is started, the
screen size is assumed to be whatever was configured in the IMF/3000
configuration file.
SNA IMF |
|
Like IMF/3000, SNA IMF allows the host to set the screen size. However,
screen size cannot be specified on the HP 3000. As part of SNA protocol,
the IBM host sends a BIND command at the beginning of a session. The BIND command, which is transparent to the user, establishes
the screen size for SNA IMF. A screen must be 480, 1920, or 3440
characters; otherwise, SNA IMF rejects it.
