=================================================================== = USB Windows COM Driver [COM-4(USB)] = = Ver2.16 = = CONTEC Co.,Ltd. = =================================================================== - Contents =========== Introduction Specification Restrictive Matter Hardware Setup Cautions Career at version up - Introduction =============== Thank you for purchasing this product. USB Windows COM Driver [COM-4(USB)] consists of the Microsoft Windows XP/2000/Server 2003/Me/98/95 device driver. The software controls the CONTEC COM-4(USB) just like the COM ports on the PC under Windows XP/2000/Server 2003/Me/98/95. Therefore you can use it in Remote Access Control(RAS). - Specification =============== Applicable OS Microsoft Windows XP Professional Microsoft Windows XP Home Edition Microsoft Windows 2000 Professional Microsoft Windows Server 2003 Microsoft Windows Me Microsoft Windows 98 Microsoft Windows 95 (OSR2) MAX ports 64 ports Applicable models IBM PC/AT Series and compatibles Applicable terminal COM-4(USB) - Restrictive Matter ===================== Please note that this product is not intended for use with Windows 95(no OSR2), Windows NT3.51, 4.0 and Windows 3.1. In some cases, the actual number of available ports depends on the number of available USB ports on the PC. - Hardware Setup ================ *ID setting The ID can be set within the following range: 0 to F - Cautions ========== * Setting COM ports You can set up the COM ports(data bits, parity, ...), using "Ports in Control Panel" or "Mode command in Command Prompt". However COM application useally sets up these parameters. * Setting COM ports No. COM port No. is allotted by OS automatically. You can change of COM port No. "Device Maneger"-"Port"-"Property"(Windows XP/2000 /Server 2003). "API-TOOL Configuration"(Windows Me/98/95). * About RAS You can use of "Remote Access Service(RAS)". See the "On Line Help" in the Windows XX or "Windows XX set up guide" for details such as RAS setting. * Programing You can use of Win32 COMM API and Communication Control(MSComm) in Visual Basic. You can use MSComm in COM1-COM16. See the language references(Visual C++, Visual Basic, Win32SDK, ...) for details such as API specification. * Range of the baud rate(bps) 2-115200 (bps) Ex.) 50, 75, 150, 300, 600, 1200, 1800, 2400, 3600, 4800, 7200, 9600, 14400, 19200, 28800, 38400, 57600, 115200 * Upper limit of the baud rate The upper limit of the baud rate which can be set is dependent on the processing capacity(operating rate) and load(simultaneous execution with another program, etc.) of the PC in use. Communications at a rate higher that the upper limit will cause communications errors(overrun, parity, framing). Check the baud rate which can be set by actually conducting communications using one of the "Hiper Terminal" utility with operating system. * Cautions for Windows XP/2000/Server 2003 Not support XON/XOFF flow. - Career at version up ======================= Ver.2.14->Ver.2.16 2010/11/19 ---------------------------- [Windows XP/2000/Server 2003] - When PC is running shutdown, PC is bluescreen of death(STOP CODE:0x0000008E). It is corrected. - Add EV_TXEMPTY event. Ver.2.12->Ver.2.14 2005/9/21 ---------------------------- - Support Windows Server 2003 [Windows XP/2000/Server 2003] - Matched it to the operation of standard COM port. - So as not to return the error even if zero is specified for a receive data size when the ReadFile() is executed, it changes. Under such a condition, even if the USB cable is pulled out after the ReadFile() is executed, and is done afterwards, the driver cannot be loaded, modified. - DTR is turned off when the port opens and DTR is turned off when it is closed to turn it on. , modified. - When MSCOMM is used, OS is a frieze in OPEN/CLOSE on the other party of the communication according to PC. The done trouble is corrected. Ver.2.11->Ver.2.12 2003/7/23 ---------------------------- - Buffer size has not been changed from 4096 bytes of a default value at the time of SetUpComm function execution (buffer size change), modified. (Windows XP/2000) Moreover, under this influence, after changing buffer size, when communication was performed, the phenomenon in which the data pointer of a buffer shifted in the place beyond the changed buffer size had occurred. Ver.2.10->Ver.2.11 2002/7/25 ---------------------------- - OS may hang up if PC performs continuation communication at the time of high load, modified. (Windows XP/2000) Ver.2.00->Ver.2.10 2002/6/6 ---------------------------- - Support Windows XP - When transmission TimeOut value is several mm second, OS may hang up after the data transmission, modified. (Windows XP/2000) - Baudrate is set up in 2400bps TeraTerm use forcibly, modified. (Windows 2000) - OS may hang up when WriteFile is done by the continuance for a long time, modified. (Windows XP/2000) Ver.1.20->Ver.2.00 2001/5/15 ---------------------------- - Support Windows 2000 - Add CommChk.exe, CtstCom.exe - The problem which ON/OFF of RTS stops being made by the timing in is modified.(Windows Me/98/95) Ver.1.10->Ver.1.20 2000/9/14 ---------------------------- - Support Windows Me Ver.1.10 1999/5/28 ------------------ - New release
