#define | ACE_HS_RTSCTS 0x0003 |
RTS / CTS hardware handshake. | |
#define | ACE_HS_MODEM 0x001F |
Full modem hardware handshake. | |
#define | ACE_HS_SOFT 0x0020 |
XON / XOFF software handshake. |
|
RTS / CTS hardware handshake. Nut/OS uses DTE definitions, where RTS is output and CTS is input. |
|
Full modem hardware handshake. Not supported yet by the standard drivers. |
|
XON / XOFF software handshake. It is recommended to set a proper read timeout with software handshake. In this case a timeout may occur, if the communication peer lost our last XON character. The application may then use ioctl() to disable the receiver and do the read again. This will send out another XON. |
