What's new in TConnector: Data Acquisition ActiveX Control 2.4.5
May 10, 2014- Bug Fixes:
- Crash in Read() - TCON-4684: Intermittent crash in Read() method of TConnector
New in TConnector: Data Acquisition ActiveX Control 2.4.4 (Oct 1, 2013)
- Enhancements:
- TCP Keep-Alive
- In previous versions a lost TCP connection could not be detected in a reasonable time. The reason was because the system default keep-alive time for TCP connections is 2 hours. Now the time interval can be specified by the user in the Service property with the following syntax: service#keepalivetime (milliseconds). The value applies to the current Winsock instance only.
- Bug Fixes:
- Multi-Threading Problem
- StopListen influences all instances of TConnector.
- BT/TCP Reconnect
- Reconnect does not work correctly when a BT/TCP connection was lost.
New in TConnector: Data Acquisition ActiveX Control 2.4.3 (May 13, 2010)
- Enhancements :
- I/O Type Bluetooth: Support for Bluetooth connections (if BTH device address is available).
- Support for Escape Zero Bytes in Read() and Write() method.
- Bug Fixes :
- Escape Zero Bytes removed last Byte from read data. Null Byte on first data position led to data loss.
- Virtual COM ports: Reading no data if serial buffer contains less Bytes than requested. Occured only with specific drivers (e.g. AVM Bluetooth Stick, BlueFritz! USB).
- Device Open now tests for read access instead of write access.
- Access sample required TBarCode 6 installed.
- Excel sample VBA (wrong error code in error handler).
- Known Limitations :
- TCP/IP does not support Timeout Infinite (this is by design of TCP/IP drivers).
New in TConnector: Data Acquisition ActiveX Control 2.3.1.29 (Jun 9, 2009)
- Keyboard stroke emulation (Keyboard Wedge).
- Now also possible in synchronous mode.
- Unicode capable
