Parameters
ReadIntervalTimeout [out] Maximum time, in milliseconds, allowed to elapse between the arrival of two characters on the communications line.
ReadTotalTimeoutMultiplier [out] Multiplier, in milliseconds, used to calculate the total time-out period for read operations. For each read operation, this value is multiplied by the requested number of bytes to be read.
ReadTotalTimeoutConstant [out] Constant, in milliseconds, used to calculate the total time-out period for read operations. For each read operation, this value is added to the product of the ReadTotalTimeoutMultiplier member and the requested number of bytes.
WriteTotalTimeoutMultiplier [out] Multiplier, in milliseconds, used to calculate the total time-out period for write operations. For each write operation, this value is multiplied by the number of bytes to be written.
WriteTotalTimeoutConstant
[out] Constant, in milliseconds, used to calculate the total time-out period for write operations. For each write operation, this value is added to the product of the WriteTotalTimeoutMultiplier member and the number of bytes to be written.
