It is not TWSocket which split packets, it is winsock. And it is perfectly normal. TCP is a stream oriented protocl. That means datagram boundaries are not preserved. There NOTHING you can do against that as long as you use TCP. You MUST build your application to assemble received packets in a buffer, probably a circular buffer and dynamically parse the buffer for the grammar used by the protocol since there is no delimiter nor any header. btw: I see that in your packet dump there is a $0A at the end of "bf2cc pl". Isn't $0A (linefeed) not the command terminator ? Line feed is the single character Unix system use to terminate a line in a text file. I also see a lot of $09 (TAB char) and $0D (Carriage Return or CR) chars. Are not those characters the delimiters you need ? You really should search for a formal definition for the protocol used. -- [EMAIL PROTECTED] The author for the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be ----- Original Message ----- From: "Waldemar Łukaszewski" <[EMAIL PROTECTED]> To: "ICS support mailing" <twsocket@elists.org> Sent: Saturday, June 24, 2006 5:04 PM Subject: Re: [twsocket] WSocket - HOW DO I...? > It's a standard header.
