'SL' | Start VFU Load

Character Printer

## Description

Use 'SL' to start VFU load. The data following 'SL' (from 'SL' up to an 'EL') defines the VFU channels.

The total number of characters defines the page length; the characters themselves represent the channels that can be slewed to. The first character must be a 1 (channel 1).
