stream data through MSComm

[shaba]

Hi,

i have been playing with the MScomm control and i have been able to get it to pass data back and forth. But i am not able to get it to process data as it recieves it. let me explain. i built a chat app with two richtext boxes. one for typing your text and one for viewing what the other computer sent. i would like to be able to type a character into the input box and have it be displayed on the remote computer right away. right now, i have to generate an OnComm event to be able to flush the buffer. i tried setting the inbuffersize to 1 and just about everything else i can think of. but i still have to push a button to generate an oncomm event and flush the recieve buffer.

please tell me if i have to live with it, or is there something i can do?

What you can do is sit in a loop

  Dim arr() As Byte  

  Do
    DoEvents
    
    If (frm.MSComm.InBufferCount > 1) Then
       arr = frm.MSComm.Input
       
       '' convert the array to a string
       '' append the string to a display box
       
    End If
    
  Loop Until False '' or some other condition

Now all you need to do is handle the sends, which can be done in the KeyPress event

Hi,

set your mscomm control to this :

inbufsiz 1024
sendbufsize 1024
rtresh : 1
do not click any option or handshake
0 in all the rest.


Oncomm()

display = display & com.input

end Oncomm


PS do not use Doevents in the Oncomm even because
your oncomm will be cutted by some other oncomm
events and the caracters may be misplaced from then
order you sent it.
