Customization Section
The customization section (found only in enhanced tables) allows you to specify
larger screen sizes, user-defined UDT names, and user-defined terminal initialization
sequences.
Restrictions for Large Screen Sizes:
For the larger screen sizes function to work,
the terminal must have the capability and be at an appropriate BC level. The
terminal installer must set up the terminal to be able to operate at the larger screen
sizes.
When the terminal does not have screen sizes that match exactly the 3270 Model 3,
4, or 5 sizes, larger screens may be used. Consult the reference manual for the
terminal you are using to determine what size can be used and the values to code in
for the set screen size sequences.
The customization section contains the following fields:
Set 24 x 80 mode sequence (model 2)
This is a 16-byte field used to define the ASCII sequence that should be
sent to the terminal to cause it to use a screen size of 24 x 80. The first
byte of the field should contain the count (in hexadecimal) of the number
of characters in the sequence. The remaining bytes of the field contain
the actual sequence to
be
sent and should
be
entered as the hexadecimal
representation of ASCII characters. If the count is 0, the 3708 will not
accept a BIND from a host application specifying a screen size of 24 x 80.
Set 32 x 80 mode sequence (model 3)
This is a 16-byte field used to define the ASCII sequence that should be
sent to the terminal to cause it to use a screen size of 32 x 80. The first
byte of the field should contain the count (in hexadecimal) of the number
of characters in the sequence. The remaining bytes of the field contain
the actual sequence to be sent and should be entered as the hexadecimal
representation of ASCII characters. If the count is 0, the 3708 will not
accept a BIND from a host application specifying a screen size of 32 x 80.
Set 43 x 80 mode sequence (model 4)
This is a 16-byte field used to define the ASCII sequence that should be
sent to the terminal to cause it to use a screen size of 43 x 80. The first
byte of the field should contain the count (in hexadecimal) of the number
of characters in the sequence. The remaining bytes of the field contain
the actual sequence to
be
sent and should be entered as the hexadecimal
representation of ASCII characters. If the count is 0, the 3708 will not
accept a BIND from a host application specifying a screen size of 43 x 80.
Set 27 x 132 mode sequence (model 5)
This is a 16-byte field used to define the ASCII sequence that should be
sent to the terminal to cause it to use a screen size of 27 x 132. The first
byte of the field should contain the count (in hexadecimal) of the number
of characters in the sequence. The remaining bytes of the field contain
the actual sequence to be sent and should be entered as the hexadecimal
representation of ASCII characters. If the count is 0, the 3708 will not
accept a BIND from a host application specifying a screen size of 27 x
132.
