Terminal Options and Attributes
TN6530 uses the TELNET protocol to communicate with the remote NonStop host system. While
establishing the connection, the emulator and remote TELNET server process negotiate options
using the TELNET protocol WILL, WONT, DO, and DONT commands. It negotiates the following
options: suppress go ahead, binary, echo, and terminal type. All terminal type options are ignored
except TELOPT_TTYPE, which is used as described in “Requesting Block Mode,” in Section 12,
Communicating With the TELNET Server.
Once the connection is established, the emulator enters full-duplex conversational mode with
character-at-a-time input mode. The emulator enters block mode only at the request of the host
processor. Some applications on the NonStop system will place your terminal in block mode.
The mode is displayed on the right side of the twenty-fifth line on your screen. TTY-FDX indicates
full-duplex conversational mode and BLOCK indicates block mode. See “Working in Conversational
Mode” and “Working in Block Mode”, later in this section, for more information.
NOTE: You can create an initialization file to override some terminal options and attributes. See
“Initializing Terminal Options” (page 147) later in this section.
Video Attributes
If your terminal is capable of supporting the following attributes, they can be used with TN6530:
• Normal video
• Reverse video
• Underline
TN6530 attempts to make use of all video attributes supported by the terminal, and it substitutes
some other attribute for one that is not supported. For example, if blinking video is not supported,
reverse video is used. If reverse video is not available, underline video is used. If underline is not
available, then normal video is used. The following attributes are tried for dim video (half intensity)
in the order indicated: underline video, reverse video, normal video.
Underline is not available on a standard Sun workstation.
When many blinking characters appear on the screen, the emulator appears to operate slowly
because it is spending most of its time performing the blinking function. To avoid this apparent
slowdown, you can disable the blinking function by putting the following line in your.tn6530init
file:
blinking off
