Hi!
I want to do a serial communication between a PC and an Oscilloscope with Windows in it.It has also got a serial port.
Can anybody help me on how to do that in C/C++/Perl/VB?
I would appreciate if a working code is explained as an example.
Thanks in advance!
-pd

If you want connect 2 PC´s, you will need a serial cross cable ( named NULL MODEM cable ). It inverts pins 2 and 3, and flow control signals pins too.
Also, if you are using - for example - C++Builder or Delphi, it have some examples in the Web using Windows API.

Hello !
You can use the " SaxComm6.ocx " for the serial communication between two PCs.

| Take a look at the CPORT libraries. I think that they work in most compilers. I have used it with Delphi and Borland builder. Works well and has many features. Easy to use

Hai
First Check the Serial Communication Between PC and Scope through Hyper Terminal in windows.If It's Working then We can easily Communicate through Vb.
Using Vb We can send and recive data in serial port easily.Using MsCOMM32 Activex Control.

hay all
i will give an idea
i use the serial port to control dot matrix desplay before
and you can mak small test on it by usingthe c languge
youmust have the MILINUM windows
and by using the port number instruction you can make amazing things
try and say hi

you can perform this connection using c\c++ using these instructions:
outp()
inp()
you shall have their prototype in c compiler help .
you only have to know the number of the serial port you are using .
you can know the number of the serial port from device manager .
you also need to know the baud rate of the transmitting/recieving com

HELLO!!!!!!!!!
I am already interested on it . I use parallel port in c++ with outportb comand
with port address 378.
Port address for serial port may be 3F8. So can we use outportb with port
address 3F8. Would it work.
Let's try & let me know what happen.

that C++ compiler you use?
Because if it is in DOS if you have to work directly with their addresses and records, but if a version of C in visual mode you have to enter the port as a file and what type in the open and then close

WinXP does not support user mode operation.
They handle all port securely so it is not possible to access port directly by addressing
in DOS by Borland c++ or others.So when I am using them to access parallel port have to download a driver and install them in system32.
Now is there any such driver available for serial port.Please some one upload it.

Hi , every body!
I'm taking a small example of communicating through RS232 using CMSComm. But it got me to trouble.
It seems that the receive buffer is never cleared when I use m_Comm.GetInput(). I can achieve the data sent to COM port but the receive buffer gonna be full and overflow. I try to catch out what's going on by adding a byteCounter and surprisingly, the total bytes I receive is exactly the size of the receive buffer.
That is, if buffer'size is 9192, I can get 9192 bytes only till I get a receive buffer overflow event. A AfxMessage is popped up for warning. Click OK then I can receive 9192 bytes more before I get another overflow event. ( so I think when AFxMessage is popped up, the buffer is cleared )
Does anybody know whu the buffer is not cleared when I read it and how to solve??? Because I'm sending a quite big file through COM port ( typically bigger than the reasonable buffer's size - up to 1MB )
Thanks in advance!!!
