Hello all,

I've been monitoring this list for a while now and have to say that 
I'm pleasently suprised with the help you get.

So for the first time I'd like to ask a question to you all:

I'm using the usart routines from Vasile Surducan to receive one byte 
at a time. But how can I best solve the problem if I want to receive 
a string? The usart buffer is only 2 bytes big and I want to send at 
least a string of 6 bytes.
The thing is, I want to send 3 command bytes followed by 3 data bytes 
to the pic. Depending on the command given I process the data bytes.

I already found a solution for this by using a simple homemade 
protocol which send the same byte back as an acknowledge before I can 
send the next byte. But this isn't standard. The nicest thing would 
be if I can send the string from a standard terminal program.

I'v been thinking about copying the received bytes into memory and 
process them after receiving the last one. But I'm not sure if that 
would be fast enough so my usart buffer doesn't overflow. The other 
way to go might be hardware flow controls but that would cost me 
extra I/O-pins that I don't want to give up.

Thanks already for all the help.

Lars
