Half-duplex modem without turnaround delay |
| 摘要 |
A modem is operated in a half-duplex mode having various elements which are trained on data and which are locked up while data is not exchanged, thereby eliminating the need for a preamble. A preamble is used only if the period between successive transmissions exceeds a preselected threshold.
