CHAPTER 4: Operation
4.3 The Terminal Display and Scroll Buffer
With the Serial Upgrade Kit, the ServSwitch Affinity implements industry-standard
VT100 terminal emulation. You can also use it in standard TTY mode and it will
automatically scroll incoming data. Figure 4-2 shows a typical screen from a UNIX
computer. The serial data from the computer is shown in the standard 24 x 80
area. Below the data are two status lines. The first line shows the current user-
station name (“NOC station 12”), user name (“Martin”), connect mode (“Share
mode”), and computer name (“Unix NCC”) that are currently in use. These fields
all reflect the Affinity’s current state.
The Affinity also implements an eight-page scroll buffer. View up to eight pages
of previous data using the page-up [PgUp] and page-down [PgDn] keys as shown
in the second status line. Use the [F12] key to clear the screen. The number of the
page to which you’ve scrolled is shown at the right of the second status line. The
two colors on the screen correspond to the background and text colors that you
can set in the Affinity’s “Configure System” page (see the “Configuring the System”
section in your Affinity manual).
