Visual Foxpro Serial Communication Rs232
The following is the code example from vfp 3.0 for this work but it seems not working. ---------------------------------------------------------------------------- --------------- *** OLE ??? *** * The following example shows how to perform basic serial port communications: * Use COM1. this.CommPort = 1 * 9600 baud, no parity, 8 data, and 1 stop bit. this.Settings = "300,e,7,2" * Tell the control to read entire buffer when Input is used. this.InputLen = 0 * Open the port. this.PortOpen = .T. * Send the attention command to the modem. this.Output = "AT" + CHR(13) * Wait for data to come back to the serial port. ii =1 DO WHILE this.InBufferCount do I miss any important setting or any other things? >Please do help me! >thx computer_2(); Tue, 22 May 2001 03:00:00 GMT Page 1 of 1 [ 2 post ] Relevant Pages 1. need to read a comm port

Now we are going to add a serial port control to the control box so that we may use it in our application. For this demonstration we are going to use the mscomm32.ocx communication driver, depending on what other MS applications you have loaded on your system, this driver may or may not be available on your system.
If you downloaded the mscomm32.ocx driver from the internet and you don't have Visual Basic, Visual Fox, or one of the other programs that it is supplied with, you don't have a registered copy and will not be able to use this driver. Don't worry, there are two other ways to accomplish serial communications that don't require this driver, continue to the other two options than don't require the mscomm32.ocx driver.

The SuperCom Suite enables one single application to setup and handle simultaneously multiple connections using serial lines, Modem, TCP/IP and ISDN. The development of mixed applications is very efficiently supported by the SuperCom Suite. Data transfer protocols only need to be developed once. It only needs one function to set the communication path ("ComType") and the rest of the used SuperCom functions remain unchanged.

Various devices have been developed to open new communicationchannels to computers. Physical motion detection devices such aschin switches [Note 1] or head gesture recognition [Note 2] havebeen employed. Eye pointing information has been used to controla computer, both through the electrooculogram [Note 3] andthrough visually evoked responses [Note 4]. The Brain-Computerinterface has recently come under attention, with efforts totrack the mu "wicket" rhythm [Note 5] and the 40 Hz pre-motorpotential [Note 6]. Pattern recognition techniques have beenapplied to the EMG signal to control prostheses [Note 7] andcomputers [Note 8].
