Appendix COM-2(PC)F 45 Sample Program 1 This GW-BASIC sample program demonstrates the transmit-data capability of COM- 2(PC)F in Enhanced mode. First, it initializes the Asynchronous Communication Element (ACE) , then it transmits the data input from the keyboard to the external device through channel 1 (CN1).
Appendix COM-2(PC)F 46 Sample Program 2 This GW-BASIC sample program demonstrates the receive-data capability of COM- 2(PC)F in Enhanced mode. First, it initializes the ACE , then it transmits the data input from the external device to CRT through CN1.
Appendix COM-2(PC)F 47 Sample Program 3 This GW-BASIC sample program demonstrates the transmit-data capability of COM- 2(PC)F in Compatible mode. Using this [OPEN " COM1 : 9600, N, 8, 2, DS" AS #1] command opens the RS-232C communication file (COM1).
Appendix COM-2(PC)F 48 Sample Program 4 This GW-BASIC sample program demonstrates the receive-data capability of COM- 2(PC)F in Compatible mode. Using this [OPEN " COM1 : 9600, N, 8, 2, DS" AS #1] command opens the RS-232C communication file (COM1).
Appendix COM-2(PC)F 49 Sample Program 5 This GW-BASIC sample program demonstrates the receive/transmit-data capability of COM- 2(PC)F in Enhanced mode. First, it initializes the ACE , it then receives the data input from the keyboard through CN1. Finally it outputs the data to C RT through CN2.
Appendix COM-2(PC)F 50 Sample Program 6 This GW-BASIC sample program demonstrates the receive/transmit-data capability of COM- 2(PC)F in Compatible mode. Using the [OPEN " COM1 : 9600, N, 8, 2, DS" AS #1] command and the [OPEN "COM2 : 9600, N, 8, 2, DS" AS #2] command opens two RS-232C communication files (COM1 and COM2).
Appendix COM-2(PC)F 51 Sample Program 7 This GW-BASIC sample program demonstrates the receive/transmit-data capability of COM- 2(PC)F in Enhanced mode with interrupt input. It calls a machine language program to register and handle interrupt input. One channel's receive/transit- data routine is processed in the interrupt handler.
Appendix COM-2(PC)F 52 Sample Program 8 [Half-duplex data transmission (Enhanced mode)] The sample program 8 enables initialization on ACE, data transmission in the transmission mode, and waits for the receive data in the receive mode.
Appendix COM-2(PC)F 53 Sample Program 9 [Half-duplex data reception (Enhanced mode)] The sample program 9 enables initialization on ACE, receives 5-byte data; after transmission, the program enters the transmission mode for data transmission.
Appendix COM-2(PC)F 54 Sample Program 10 [Data transmission and reception (COM1, COM2 mode)] Sample program 10 uses the bios_serialcom ( ) function for MS-C. It first receives the data transmitted from COM1, and then receives the data at COM1 transmitted from COM2.
Appendix COM-2(PC)F 55 Sample Program 11 [Data transmission and reception (COM3, COM4 mode)] Sample program 11 uses the bios_serialcom ( ) function for MS-C. It first receives the data transmitted from COM3, and then receives the data at COM3 transmitted from COM4.
Appendix COM-2(PC)F 56 B. Notes on Developing Driver Software Internal Registers COM- 2(PC)F uses the NS16550 (National Semiconductor) as the Asynchronous Communication Element (ACE). Within the address range of each channel, the offset addresses 0 through 7 furnish access to the internal registers of each of the two ACE's.
Appendix COM-2(PC)F 57 Baud Rate Selection The COM- 2(PC)F board has one programmable baud rate generator for each of the two ACEs. The ACEs use a 1.8432MHz crystal oscillator as clock input. The baud rate generator takes the 1.8432MHz clock and divides it by a divisor from 1 to (2 16 - 1).
Appendix COM-2(PC)F 58 LSI Recovery Time Due to the ever higher CPU clock rates used in PCs, restrictions apply when controlling a peripheral LSI device by software. Table 6.8. lists the LSIs used on CONTEC boards which require special consideration when accessing.
Appendix COM-2(PC)F 59 Example program (for accessing an i8254 or equivalent) - Microsoft Macro Assembler OUT DX, AL ; Access to the i8254 IN AL, 2EFH ; Execute IN AL, 2EFH once to provide the recover.
Appendix COM-2(PC)F 60 V arious Aspects of Interrupt Handling in Enhanced Mode and Compatible Mode Enhanced Mode When in Enhanced mode, two channels of the COM- 2(PC)F share the same interrupt request line. The interrupt levels can be set from IRQ3~IRQ7, IRQ9~IRQ12, IRQ14, and IRQ15 by setting JP1 before installing this board.
