Intercharacter-delay operating mode
The intercharacter delay operating mode provides a means of communication
control by delaying the transmission of label data. The scanner delays the trans-
mission of each succeeding character by a fixed, configurable amount.
For details of the intercharacter delay operating mode, see Figure 4-4, Figure 4-5,
and Figure 4-6.
