* arch/arm/src/tiva/common/tiva_serial.c: (up_ioctl): PR #8406 (commit 1edec0aaa1) added support for configuring the serial port's CTS/RTS flow control at runtime using termios when built with CONFIG_SERIAL_TERMIOS and either or both of CONFIG_SERIAL_OFLOWCONTROL and CONFIG_SERIAL_IFLOWCONTROL. However, a runtime sanity check left over from before prevented this from working: When processing ioctl TCSETS, we would return -EINVAL if one or both of CCTS_OFLOW and CRTS_IFLOW were requested, which was not deserved if the requested features were in fact supported. Fixing the sanity check so it depends on features actually configured. |
