SERIAL PORT CONTROLS¶

These are controls for serial port settings. These are received on the server side only. It should respond by setting the value (if possible and the value isn't zero) and responding with the current value with sergensio_xxx().

GENSIO_EVENT_SER_BAUD
GENSIO_EVENT_SER_DATASIZE
GENSIO_EVENT_SER_PARITY
GENSIO_EVENT_SER_STOPBITS
GENSIO_EVENT_SER_FLOWCONTROL
GENSIO_EVENT_SER_IFLOWCONTROL
GENSIO_EVENT_SER_SBREAK
GENSIO_EVENT_SER_DTR
GENSIO_EVENT_SER_RTS

SIGNATURE¶

GENSIO_EVENT_SER_SIGNATURE is received on the server side only and is a request for the signature. The server should respond by send the signature with sergensio_signature(). No value is passed in this case.

STATE FUNCTIONS¶

GENSIO_EVENT_SER_MODEMSTATE_MASK
GENSIO_EVENT_SER_LINESTATE_MASK
These are received on the server side to request updating the mask of reported values. The server should respond by returning the current mask with the sergensio_modemstate or sergensio_linestate functions. The server need not handle all the bits requested by the user.

GENSIO_EVENT_SER_MODEMSTATE
GENSIO_EVENT_SER_LINESTATE

On the client side, these are reporting current modemstate and linestate changes as an unsigned integer. See sergensio_modemstate(3) and sergensio_linestate(3) for a meaning of the bits in the integer.

OTHER SERIAL PORT CONTROLS¶

These are server-only, these are received requesting the various operations. The server should do them, but no response is required. You may notice that break is not here, break is handled through the GENSIO_EVENT_SEND_BREAK event.

GENSIO_EVENT_SER_FLOW_STATE
GENSIO_EVENT_SER_FLUSH

SYNC¶

GENSIO_EVENT_SER_SYNC is a special operation that comes in when a TCP sync event is received. It may be received on both sides. A server should send a break. The client can do whatever it wants with the information, that is not defined by the RFC2217 specification.
