Using Visual on HP-UX
Visual mode should work on HP-UX, providing you have an HP terminal or an HP terminal emulator. You must configure your terminal for Transmit and Receive XON/XOFF Pacing or you risk file system errors.
You must also configure the host prompt to be a DC1 (Control-Q). Because there are few block-mode applications for HP-UX, the host prompt is often configured as null.
