ok after restarting everything, your suggestion works perfect.  Before I restarted, the data was out of order.  The 0A 3E was at the beginning.  It's odd that it keeps what was not sent in a buffer till the next send.  I don't know if it is the emulator or the software I'm sending to doing that but thank you so much for your help!

I am trying to send data to a program that can only accept 16 bytes at a time.  My file contains this:

"
-02004C6B30
>"

There is a carriage return at the beginning and carriage return before the > but not one after.

It should show up as this:

"0D 0A 2D 30 32 30 30 34 43 36 42 33 30 0D 0A 3E"

but instead is shows up as this when sent 10 times:

The data get shifted 2 bytes over per send till it loops back to what it was supposed to be.  As you can see there are only 2 carriage returns in my data I am sending but the emulator is adding a third one at the end.  How do I eliminate the 0D 0A it sends at the end of the command?

Thanks
