So I am trying to connect to a piece of hardware. If I connect and disconnect with hyperterminal first. Then close the connection and the program.
Everything works fine. If I don't I receive random characters back from the hardware. I use the same settings in hyperterminal as I do in the code. Baud=9600 parity=n data=8 stop=1 Hardware flow controls 'ON': octs=on to=on dtr=on rts=hs If I then disconnect the hardware and the serial port I will have the same problem again. Is there anyway I can see how to comport is being configured after hyperterminal open and closes the port?
I should note I am using a prolific serial to USB adapter. Below is the code I use to open the com port. Function OpenCom(PortNum As Integer, Baud As Long) As Long Dim lpDCB As DCB Dim ComTimeout As COMMTIMEOUTS com$ = 'COM' + Trim(Str(PortNum)) 'open the communications port hcomtemp& = CreateFile(com$, GENERIC_READ Or GENERIC_WRITE, 0, ByVal 0, OPEN_EXISTING, 0, ByVal 0) 'check for errors If hcomtemp&.
Introduction is a program that you can use to connect to other computers, telnet sites, bulletin board systems (BBS), online services, and host computers. HyperTerminal connections are made using a modem, a modem cable (used to emulate modem communication) or an Ethernet connection. HyperTerminal has other features than connecting to other computers. It can, for example, transfer large files from a computer to your laptop using a serial port instead of requiring you to set up your laptop on a network. It can help debug the source code of a remote terminal.
It can also communicate with old computers based on characters. HyperTerminal records messages sent to and from the computer or service at the other end of your connection.
It can therefore serve as a valuable troubleshooting tool when configuring and using your modem. To make sure your modem is properly connected or to view your modem settings, you can send commands via HyperTerminal and check the results. HyperTerminal also has a scrolling feature that allows you to view the received text that has scrolled off the screen. Since the version, Hyperterminal is not included with Windows.
