What version of Indy are you actually using?  It makes a difference in how 
the code has to look.

What type of members does CLIENTTOSERVERCMD actually contain?

Do not use the Socket property directly like that.  TIdTCPConnection (which 
TIdTCPClient derives from) in Indy 9, and TIdIOHandler in Indy 10, have many 
reading/writing methods of their own that you need to use instead.  For 
instance, in Indy 9, you could use TIdTCPConnection::WriteBuffer(), and in 
Indy 10 you could use RawToBytes() and TIdIOHandler.Write(TIdBytes) instead.
