#85730 - how have you wired the MAX232 up? Responding to: ???'s previous message |
Also, what happens when you connect the tx and rx pins together on the 89c52 side of the max232? If you use a terminal program on the PC, what you type should get echoed back. Disconnect the rx and tx pins and the echo should stop. This tests the MAX232 operation. |
