ABSTRACT:
A message packet transmitter for transmitting a packet of electronic data signals onto a communication network without interruption. A first-in, first-out electronic memory has a transmit state in which an electronic data signal stored therein is output. The electronic memory has an idle state in which electronic data signals stored therein are not output. A message packet-in-transit identification circuit generates a packet-in-transit signal after the electronic memory outputs the first electronic data signal in a message packet. A no-packet-in-transit signal is generated after the electronic memory outputs the last electronic data signal in the message packet. A state controller maintains the electronic memory in the transmit state when the electronic memory stores at least a portion of a message packet, when the state controller receives a packet-in-transit signal, and when the state controller receives an interrupt-pending signal.
