Socket reading problem

[Len Morgan]

I'm trying to read data from a socket.  The data is Modbus/TCP.  The 
first routine I tried is

read from socket pSock for 3 uInt2s

This gives me no data (both "it" and "the result" are empty).  I know 
the packet has been received and there is data after these 3 numbers.  
If I change this
to:

read from socket for 6 chars
put it into tData
put binaryDecode("m3", tData, tSeq, tProto, tBytes)

then tSeq, tProto, and tBytes get the right data in them.  I have tried 
the first method with and without a callback message to no avail.  Am I 
missing something?
