serial Send speed

Isn't it easier to set 255 as termination char?

[Ranjeet_Singh]

He / she needs to start reading when 255 encountered

[V.S]

I did that but the transfer rate didn't change... (3 or four sets per seccond).

[Yamaeda]

Well how big is a set? How much data is discarded? How much data do you actually recieve?

2MB ~ 200kb of text.

/Y

[Yamaeda]

I added a little information, how does this work?

[V.S]

I attached an image from the front pannel when the program is running.

as you see the "bit/sec" indicator shows 188717 but it sometimes changes to 188008 bit/sec.

What is the problem? You are successfully communicating at 2Mbaud. You don't get any errors. You don't get a buffer overflow so it would appear you are keeping up with whatever is transmitting.

What is actually transmitting? How big is each packet? How often is each packet sent?

[V.S]

It's supposed to recieve 2,000,000 bit in every seccond but as you see in the JPG file the transfer rate is 188717bit/sec not 2mb/sec!!!

The transmeter sends data in a row continusly and the VI should start to read 5000bytes after recieving a "FF" byte and then after recieving consequent "FF" it recieves another 5000bytes and so on....

[RavensFan]

No.  Your indicator is showing BYTES per second.

It looks like you should have about 11 bits per byte based on having 1 start bit, 8 data bits, and 2 stop bits.

[LV_Pro]

In other words ~2,000,000 bits/sec, or ~188717 bytes, with start and stop bits.
