Workstation Configurator — Screen and Field Definition
Flow Control
• 0 — delayed. If 0 is entered, the HP 3000 will wait to send an
XOFF until 16 characters are received after the typeahead buffer
is full. HP recommends delaying the sending of an XOFF if data
switches are used in the computer network.
• 1 — immediate. If 1 is entered, the HP 3000 will send an XOFF
after each character is received when the typeahead buffer is full.
• Block mode support. This field lets you configure the type of block
mode your terminal will use. The types of block mode are none, line,
page, or both. If block mode is used, the values for the block mode
trigger and alert characters are displayed.
• Read trigger character. This field lets you configure the read
trigger character. This character lets the terminal know that the
HP 3000 system is ready to receive data. If the field is left empty,
then no trigger character is written by the driver at the beginning of
a read.
NOTE The block mode read trigger character and the read trigger character
should be the same. For example, if the block mode read trigger
character is DC1, then the read trigger character should be DC1.
