Hello Friends,

I have created code,
which receives data from the comport form another sys

My program is working, but 20% of data are lost during
travelling from another sys to my system.

What is the exactly problmes with it.

I think it is a buffer error, but i chang it and try
againg but got same problems

If u know

Thanks in Advance

I believe that there is a way to have the recieving machine tell the sending machine whther it is ready to receive more or not. It appears to me (given the limited info I have at this point) that your process is either too slow to handle the data coming, or is being hit with data when it is not ready.

A second issue might be that you need to force the receiving machine to prohibit other processes from gaining access to processor time while you are receiving.

Thanks for your reply

Actually I have already developed hyper terminal program in visual basic 6, it receives data from comport 1, but opposite pc sends data at a very high speed, and I am using textbox to enter data

So textbox speed is slow, between this I lost my data.

So i want suggestion for this, how to solve this problem of lost of data in the buffer or in the processing.

Thank you very much again

hey adarsh

u need to sync b/w two machines to resolve this issue

firstly, sync the RThreshold and SThreshold (MSCOMM properties) for both the machines
then, implement Acknowledgement procedure so tht Sending machine can send next data only after receiving ACK from Receiving machine

it may be little slow but its effective

i hope it will help

ashu

Thank you very much to all friends,

with the greatest support of you i have completed my hyper terminal

Thank you very much

sortly i will give my more detail to u

Thank you very much again
