SEND ON-LINE
Sending on-line from your buffered 43 is accomplished
in either of two communication modes, S/R (Conver­
sational) or Send (Batch).
In Full Duplex S/R, the KP is actively on-line sending
from the keyboard while the printer prints received
data. In Half-Duplex S/R, only alternate two-way
communication (ie, either sending or receiving)
should be attempted to avoid interspersing of charac­
ters.
In Send mode, data is transmitted from the send
buffer either from an attendant command or upon
receipt of a start sending code (StrSn)
as
program­
med in the user option memory. In the Send mode,
the keyboard is disabled on-line.
