• Receiving Control and Buffering
The CBM-920, on receiving of print data, performs receiving control (DTR control) in one-word unit.
At this time, when the host side has performed data transmit as ignoring DTR, overrun of received data
can take place. This state should be avoided by the host side on its own responsibility. (No follow-up
can be applied to a data effluent type host.)
