#84839 - Two 8052 Responding to: ???'s previous message |
Wong said:
Is it possible to use a 8051/89C51/89C52 to drive 2 different serial COM ports? You could use the UART of a second 8052, like AT89C2051 (20pin) or similar. You could even outsource some of the according signal handling to this 'slave'. Kai |
