| Summary | 0003917: UART5 can transmit data if CTS asserted | ||||
| Description | UART5 can transmit data if CTS asserted | ||||
| Steps To Reproduce | 1. when testing UART2 (COM2) which is RTS/CTS, when we send a message without connecting anything at the end of the UART connector, if we force the CTS signal to 0V at TTL level (or +5V at RS232 level), the system is able to send a message, that is, I'm able to see the message on the TXD pin. 2. when testing UART5 (COM3) which is RTS/CTS doing the same experiment, we're NOT able to see the message on the TXD pin. This UART, UART5 (COM3) is the one that manages the modem, and we think this is the reason why the modem is not answer to the AT commands (if we work with UART2 (COM2) the modem answers the AT commands) | ||||
