The wclSerialTimeouts type exposes the following members.
Fields| Name | Description | |
|---|---|---|
 | ReadConstant | A constant used to calculate the total time-out period for read operations, in milliseconds. For each read operation, this value is added to the product of the ReadMultiplier member and the requested number of bytes. A value of zero for both the ReadMultiplier and ReadConstant members indicates that total time-outs are not used for read operations. |
| ReadInterval | The maximum time allowed to elapse before the arrival of the next byte on the communications line, in milliseconds. If the interval between the arrival of any two bytes exceeds this amount, the Read operation is completed and any buffered data is returned. A value of zero indicates that interval time-outs are not used. A value of UInt32.Max, combined with zero values for both the ReadConstant and ReadMultiplier members, specifies that the read operation is to return immediately with the bytes that have already been received, even if no bytes have been received. |
| ReadMultiplier | The multiplier used to calculate the total time-out period for read operations, in milliseconds. For each read operation, this value is multiplied by the requested number of bytes to be read. |
| WriteConstant | A constant used to calculate the total time-out period for write operations, in milliseconds. For each write operation, this value is added to the product of the WriteMultiplier member and the number of bytes to be written. A value of zero for both the WriteMultiplier and WriteConstant members indicates that total time-outs are not used for write operations. |
| WriteMultiplier | The multiplier used to calculate the total time-out period for write operations, in milliseconds. For each write operation, this value is multiplied by the number of bytes to be written. |
