Chapter 2 23
Modifying a Terminal or Printer Type File
Step 3: Configuring Flow Control
6. Type the number of seconds, from 1 to 255, that the timer will be
enabled for. This is the amount of time the HP 3000 will wait for the
XON from the terminal or printer.
To disable the XON/XOFF protocol:
1. Verify that the cursor is in the Does driver use an XON/XOFF
protocol (Y,N) field. Type N.
To specify the typeahead buffer behavior:
1. Verify that the cursor is in the Typeahead buffer behavior for
sending second XOFF field. 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.
2. Type 0 to delay sending an XOFF to the terminal after the
typeahead buffer is full. If 0 is entered, the HP 3000 will wait to send
an XOFF until 16 characters are received. HP recommends delaying
the sending of an XOFF if data switches are used in the computer
network.
3. Type 1 to specify that an XOFF should be sent to the terminal after
each character is received when the terminal buffer is full.
To configure block mode:
1. Press the
[Tab] key to move the cursor to the Block mode support
(N, L, P, B) field. Type the first letter of the block mode that this
terminal type file will use. The types of block mode are none, line,
page, or both.
2. Verify that the cursor is in the Characters: alert field. This is
the character that the terminal uses to alert the system that a block
of data is coming.
3. Type the alert character for this terminal type file. In most
instances, this character is the DC2.
4. Verify that the cursor is in the Characters: trigger field. This is
the character that the system uses to tell the terminal that it is
ready to receive the data.
5. Type the trigger character for this terminal type file. In most
instances, this character is the DC1.
To configure a read trigger character:
1. Press the
[Tab] key to move the cursor to the Read trigger
character field. This character tells the terminal that the HP 3000
is ready to receive data.
