Missing Data

[Camm29]

Help !

I'm using

Open file "COM1:"
read from file "COM1:" until empty
put it into Received
Close file "COM1:"

If the hardware i'm talking to on RS232 is set to echo sent commands it works fine and i get all the data.

If i set the hardware not to echo sent commands then most of the data is missing ?

example.

if i send "ATZ" to the Hardware with echo on,
i receive 

ATZ
HELLO
>

if i send "ATZ" to the Hardware with echo off,
i receive

>


The data HELLO > is ALWAYS sent by the Hardware after sending ATZ  but goes missing in Revolution !!!.
