Synaser is 'brother' of Synapse TCP/IP Library. It priovides same communication principes as used in Synapse, but Synaser is for serial ports, not for TCP/IP.News:fixed wrong access mode under Linux.fixed handshake problems on some Windows.added option for testing presence of device before any communication requests.Option for serial port locking under Linux.Modem support now working also with modem used as line terminator only CR instead CRLF.lot of another bugs and added next speed performance.This is list of basic features:SynaSer is not components, but only classes and routines. Not needed any installation.Working under Windows (Delphi or C++Builder) and under Linux (Kylix).Support for communicating on serial ports in blocking (synchronous) mode.Supported is high speed of communication (about few megabytes per second).Consume very low CPU time.Supported is same communication mechanism as used in Synapse TCP/IP library.Can lock serial port under Linux (like Windows do it).Support for software and hardware handshake. You may open any COM port, if exists in you system (i.e. COM156).Support for RTS driven communication (good for RS485 convertors, etc.).Option for detect device presence before each data transmission.
