Synapse串口同步库。功能有：它不是控件，而只是代码库。适合编写控制台应用服务或其它应用；不需要安装；读写数据的方法和Synapse提供的TTCPBlockSocket一样；支持MODEM的AT指令；支持RTS驱动的通讯（例如：RS-485适配器）。功能无限制。源代码：包含。适用语言：CB3 CB4 CB5 D2 D3 D4 D5-Synapse serial synchronous library. Function: it is not control, but only code base. Suitable for the preparation of the console application services or other applications do not need to install read and write data and Synapse as provided TTCPBlockSocket support the AT commands MODEM support RTS-driven communications (for example: RS-485 adapter). Features unlimited. Source code: contains. Applicable language: CB3 CB4 CB5 D2 D3 D4 D5
