Top of list Index page Interrupt 0x14 service 0x85: Enable/disable UART transmitter Parameters AH AL DX Enable/Disable UART transmitter 0x85 0: disable transmitter 1: enable transmitter Port number: 0 for EXT, 1 for COM Return Value none Comments Top of list Index page By default the transmitter is enabled. Interrupt 0x14 service 0xA0: Get number of Tx bytes in UART Parameters AH DX Returns the number of bytes which are currently in the UART transmitter hardware. 0xA0 Port number: 0 for EXT, 1 for COM Return Value Comments AX= Number of bytes in the UART transmitter hardware With this function you can check how many bytes are currently in the UART. This could be necessary to know if your communication pauses because of a handshake problem. The GetDriverInfo API (0x1B) reports the number of bytes remaining in the serial port driver's software Page 340 / 400
Top of list Index page send queue. This function reports the number of bytes currently in the UART transmit hardware. By adding this function's return value to the software transmit buffer byte count reported by the GetDriverInfo API, you can determine the total number of transmit data bytes still pending output. The maximum count returned here will be 2 bytes, accounting for the UART's transmit shift register (1 byte) and transmit holding register (1 byte). Interrupt 0x14 service 0xA1: Install a Fossil User Callback Function Parameters AH DX ES:DI The user callback function will be called when a Fossil serial port event occurs. 0xA1 Comments Port number: 0 for EXT, 1 for COM Pointer to the User Callback function This call installs an user callback function for the specified serial port. The callback function must be very short! Long Fossil callback functions can lead to character loss. To use the Fossil callback functions, you have to switch the serial port into the IRQ Mode (see CHIP.INI). In DMA mode the callback functions will not work! The callback function must conform to this prototype: fossil_event_t far *(huge my_fossil_callback)( fossil_event_t far *e ) ; The fossil_event_t structure e passed in contains the event which has occurred. Following events are possible: #define FE_DATA_AVAIL 0x01 // New Data Received #define FE_READY_FOR_SEND 0x02 // (currently not supported) #define FE_ERROR_DETECTED 0x10 // (currently not supported) Newly received data_length bytes can be found at location referenced by data pointer in structure e. The callback function can also return a fossil_event_t structure. The returned structure contains an action event which the Fossil serial port driver will respond to as follows: #define FE_IGNORE_DATA 0x01 // Do not copy the received data // into the receive queue. #define FE_DATA_TO_SEND 0x02 // (currently not supported) If the callback does not return any event, the return value must be a null pointer (=0L).
