I am working with an application to allow multiple TCP/IP clients to connect to the DigiME, sending/receiving data from a single serial server on the other side.
The TCP clients send requests for status information from the server on the serial side. Periodically the TCP client will only receive back a partial response. Not until the next request is sent do I get back the tail end of the response in addition to the following response.
The application has a thread which does the read() of the serial port, a thread for each TCP client, and a seperate thread to handle add/delete of clients. The serial port is running at 19200 baud, 8N1. I have tried different flow control settings, and functions like tcflush and tcflow with no change in behavior.
Any ideas what might be going on here or what else I could try? I can provide code snippets for anyone willing to take a look. Anyone else have a sample app that provides the same funtionality? (multiple TCP clients)
