Session Parameters
These parameters correspond to setup choices on a VT340 terminal.
- Online/Local
- In the Online state, the emulator receives data from the host computer, and can send data to it. In the Local state, data you enter on the keyboard appears on the screen, but is not sent to the host; data from the host is held, and not presented on the screen until you change the state to Online.
- Operating Mode
- Select Char if the host does not echo
the characters you type on your keyboard. The VT emulator displays
them as it sends them to the host.
Select Echo if the host echos your keyboard characters for display. The VT emulator displays them only as they return from the host.
If you see doubled characters, you should select Echo instead of Char. Echo is the default.
- Machine Mode
- There are four machine modes. These are:
- VT340 mode, with 7-bit controls
- This is the default. This mode is recommended for most applications.
- VT340 mode, with 8-bit controls
- The emulator is set for an 8-bit environment with 8-bit controls.
- VT100 mode
- This mode is intended for situations requiring strict compatibility with the VT100 terminal. In general, the VT340 7-bit mode is appropriate for applications that expect a VT100.
- VT52 mode
- This mode is only for applications designed for the VT52 terminal.
