The user may change the default port editing setting (TTY) for access ports on the terminal server. To change the parameters for the AUX port, Telnet port(s), or Modem port(s), issue the SA, ST, or SM commands for each port respectively, and change the “Terminal Emulation” parameter by toggling from TTY to VT-100.

NOTE: Your terminal must support VT-100 mode. If you issue the VT ON command, and your terminal does not support this mode, unpredictable results, such as the appearance of extraneous characters, may occur. If you have a VT-100 terminal (or your computer is emulating a VT-100 terminal) but you have the parameter VT100 On/Off set to Off, TTY mode is used and the configuration screens are displayed one line at a time.

TTY Mode

Information is displayed one line at a time for editing. After the Enter key is pressed the next line is displayed for editing. In this mode it is impossible to return to "entered" lines to modify them.

VT-100 Mode

If you have a VT-100 terminal (or your computer is emulating a VT-100 terminal) you can execute SYSOP commands in VT-100 mode. In this mode all of the prompts will be displayed on the screen at once along with the data to be edited. The cursor will initially appear at the beginning of the first field.

At this point the arrow keys can be used to move from line to line performing edits in any order. Pressing the Enter key with the cursor on the last line of the display completes the function.
