UNIX for Dummies Questions & Answers

I have no problem of sending data, i have problems of receiving data, because of buffer limit or textbox limit

Sending is successful

now i am checking for richtextbox for the same my code

if you have another choice except textbox and richtextbox please tell me.

Thanks,

The stop bit is sent by the receiving system to tell the sending system to stop sending.
Consider this:
You are filling a pail of water from a garden hose that is 100 feet from the tap, how soon do you have to leave the pail to turn the water off so that the pail is not overfilled?

No, the stop bit is just part of the encoding of a single character. A character comprises..

1. start bit
2. seven or eight bits starting with bit zero
3. parity bit if required
4. one, one and a half or two stop bits

I think you are refering to X-on/X-off (ctrl-S/ctrl-Q) and this may either be handled by serial application code or the driver itself.

Porter, you're right, poor choice of words, but he did say that he created his own code, and that his program is more or less working, so maybe we should ask him what language this is all written in?

Thanks for your reply,

I have created this software in Visual Basic 6.

now my program is working about 90% but 10% I lost data. as follow

for example opposite pc sends below data
101 101 202 302 302
102 1232 2323 323 323
103 12 12 12 12
104 101 202 302 302
105 1232 2323 323 323
106 12 12 12 12
107 101 202 302 302
108 1232 2323 323 323
109 12 12 12 12
110 101 202 302 302
111 1232 2323 323 323
112 12 12 12 12

and my program can add data like below
101 101 202 302 302
102 1232 2323 323 323
103 12 12 12 12
104 101 202 302 302
232 2323 323 323
106 12 12 12 12
107 101 202 302 302
109 12 12 12 12
110 101 202 302 302
1232 2323 323 323
112 12 12 12 12


So my program is missing 10% lines due to slowly adding of text in to textbox or richtextbox.

Please guid me what to do for this.

Thanks,

The Win32 APIs GetCommState and SetCommState will let to change the flow control handling of a serial connection. Of course both parties on either end of the serial cable need to be using the same flow control mechanism.

Ok I will check for this api and will post

Thank you
