Serial port receive buffer overflow

Response Code:

Binary: [1 1 0 1 1 1 1 1] [1 0 0 0 0 0 1 1]

Description:

The CTS hardware flow control signal from the Slink-e was ignored and the host computer continued to send data, causing data to be lost (discarded). One message is sent for every overflowed byte. Solution: Use proper serial port hardware settings. See serial port setup section. FYI, the Version 1.0 of the Slink-e has a 55 byte receive buffer. Flow control is initiated when the first 23 bytes are filled, leaving a margin of 32 bytes in which the host must recognize the CTS signal before overflow occurs. In house testing has shown that this is more than sufficient for operation in Win95 and Win NT 4.0. This is considered a critical error and causes the Slink-e to enter the resume state.
