Figure 4-12 Inbound Message with Control Character
All messages go to the receive buffer first. Form messages go on to the compose buffer. The
exception to this is the expanded functions, which behave the same regardless of the form/non-
form portion.
The portion of the control code that enables barcode or aux input is not used when sending a form
message because the form label indicates what is enabled.
