Hello, In my app (D6), I use the Indy components TIdTCPClient and TIdTCPServer to communicate using an application specific protocol. The protocol is designed similar to standard internet protocols, using text commands that require text response. With NT, everything used to work OK, but with XP I have a mysterious problem. For some commands the server produces a multiline response. On the server side, for all of these commands, all lines of output are correctly generated by the server and correctly written to the connection. But for some of those commands, only the first line of the response can be read by the client. Reading the rest of the response leads to a timeout. In my efforts to debug this, I have the client send a second command to the server and read the response to that command. But, in stead of the response for the second command, the client receives the 2nd line of the response of the first command. An attempt to read the 3rd line after that, also leads to a timeout. It would take another command to be sent to the server to be able to read that 3rd line.
The strange situation is, that this anomaly occurs but for a few of the implemented commands. On the server side, these are handled in the OnExecute handler of the TIdTCPServer and this is done the same way for all commands. To eliminate the possibities of bugs in the client app, I used PuTTY in raw mode to send commands to the server. If I run PuTTY on NT, it works, on XP it doesn't work. I tested it with the server on XP, NT, or Win2000, but that doesn't make a difference. Has anyone encountered something like this before?
