Terminals That Can Be Used with Pass Thru Any terminal supported by Pass Thru requires 8K of memory. Multipoint terminals require 12K of memory for Pass Thru: 4K for multipoint itself and 8K for Pass Thru. This section is divided into the following sections: Features of Pass Thru Terminals describes some of the features that Pass Thru terminals may have. The tables in this section that list the terminals supported by Pass Thru also indicate which features each terminal has. Multipoint Terminals lists the terminals supported by Pass Thru that work with the Multipoint Terminal Software (MTS) product. Asynchronous Data Communications Terminals lists the point-to-point terminals supported through a connection to an Asynchronous Data Communications Controller (ADCC) or Asynchronous Terminal Processor (ATP). Datacommunications and Terminal Controller Terminals lists the point-to-point terminals supported through a connection to a Datacommunications and Terminal Controller (DTC). Both English-language and Asian-language DTC terminals are listed. Features of Pass Thru Terminals This appendix contains a set of tables listing the terminals that can be used with Pass Thru. For each terminal listed, these tables indicate whether the following features are supported in Pass Thru: * Security Video * Shifted Function Keys * Softkey Label Display * Auto Keyboard Lock and Send Cursor Position * Modified Data Tags Security Video. Pass Thru supports security video for non-displayinput fields on certain HP terminals. With security video, data typed in a non-display field is not displayed on the screen. The "Security Video" column in tables C-1, C-2, C-3, and C-4 indicates whether a terminal supports security video. See "Non-Display Input Fields," in chapter 5, for more information on security video. ShiftedFunction Keys. HP terminals have 8 function keys. Some HP terminals allow you to use the SHIFT key to create uppercase and lowercase function keys, giving you 16 instead of 8. The "Number of Function Keys," column in tables C-1, C-2, C-3, and C-4 indicates the number of function keys a terminal supports (8 or 16). Softkey Label Display. Some HP terminals will display softkey labels in windows on the screen, to tell you which softkey functions your function keys have at the current level. These softkey labels have defaults, or you can configure them in the PTCONFIG file (see chapter 2). The "Softkey Label Display" column in tables C-1, C-2, C-3, and C-4 indicates whether a terminal will display softkey labels on the screen. Auto Keyboard Lock and Send Cursor Position. Some HP terminals have a feature called Auto Keyboard Lock. When you press the ENTER key on one of these terminals to transmit data, the keyboard is automatically locked until a response is received from the IBM host. Then, the HP 3000 sends an instruction to the terminal that unlocks the keyboard. Terminals with the Auto Keyboard Lock feature also have a feature called Send Cursor Position. When data is transmitted from these terminals, the exact cursor position is sent with the data, telling the IBM host where the cursor was when the keyboard was locked. The "Auto Keyboard Lock/Send Cursor Position" column in tables C-1, C-2, C-3, and C-4 indicates whether a terminal supports the Auto Keyboard Lock and Send Cursor Address features. Modified Data Tags. When using Pass Thru, you should keep in mind the differences between a terminal with the Modified Data Tag (MDT)feature and a non-MDT terminal. An MDT terminal transmits all changed data fields, including data fields that are overwritten by identical data. A non-MDT terminal transmits only those fields that are different from the internal screen image, which contains the data last written to the terminal by Pass Thru. Fields on a non-MDT terminal that have been overwritten with identical data are not sent to the host, because the data does not differ from the data in the internal screen image. When the IBM host sends null characters, the nulls are translated to blanks for your HP terminal. If you are using a non-MDT terminal, and you type some blanks into a field that previously contained nulls, the HP 3000 compares the data from your terminal with the internal screen image and finds no difference. The data appears to be unchanged, so the HP 3000 transmits no data to the IBM host.
NOTE If you are currently using non-MDT terminals, you should consider upgrading to MDT terminals. MDT terminals will transmit blanks that have been typed over nulls. They will also improve performance, because data from the terminal does not have to be compared with the internal screen image before it can be sent to the host. If you are using an HP 700/94 terminal, a ROM module (part #5062-1306) is now available that allows it to support null characters just like an IBM 3278 display station.
In tables C-1, C-2, and C-3, the "MDT/Non-MDT" column indicates whether a terminal supports the Modified Data Tag (MDT) feature. Currently, all HP Asian terminals and PCs function as non-MDT terminals. Multipoint Terminals Table C-1 lists the terminals supported by Pass Thru that work with the Multipoint Terminal Software (MTS) product. Multipoint terminals require 12K of memory to run Pass Thru: 4K for multipoint and 8K for Pass Thru. A 264x terminal must have the Display Enhancementsoption installed, and if non-display fields are used, slot C must be empty. The HP 2626A cannot display charactersin half-bright. Table C-1.

When the HP 2645A terminal is used as a point-to-point terminal, strap H must be in on the Keyboard Interface PCA. The HP 150 terminal is supported as a 24-line terminal only. Table C-2.
