The Flow Control screen lets you configure the following functionality: Driver uses an XON/XOFF protocol (Y/N).
This field lets you turn on or off the XON/XOFF protocol. If XON/XOFF
is enabled, you can specify whether a timer is started when the
XOFF is received. You can also specify the length of the timer period,
in seconds. Valid timer periods range from 1 to 255 seconds. Typeahead buffer behavior for sending second XOFF.
The HP 3000 sends an XOFF to the terminal when its typeahead buffer
is full. The value entered in this field specifies how often the
HP 3000 will send an XOFF, after its typeahead buffer is
full. 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. |  |  |  |  |
