通过串行通讯java发送数据包 [英] sending packets over serial comms java
问题描述
我正在编写一个Java应用程序，该应用程序通过串行端口与外部设备进行通信.
I'm writing a java application that communicates with an external device over a serial port.
我认为我可以连接到设备&可以发送/接收数据(我目前无法访问该设备.我正在使用仿真器)
I think I can connect to the device & send/receive data ok (I don't have access to the device at the moment..I'm using an emulator)
我只需要一些有关如何格式化要发送的数据的建议.
I just need some advice on how I should format the data I'm sending.
规范说它应该以字节格式发送.所以，如果我有类似下面的数据包要发送
The spec says it should be sent in byte format..So if I have something like the following packet to send
AA | 0D | 07 | 09 | 0A | 0B | 03 | 01 | 02 | 03 | 04 | CSM | CSM
AA|0D|07|09|0A|0B|03|01|02|03|04|CSM|CSM
这是我应该做的事情
outputStream.write((byte)0xAA);
outputStream.write((byte)0x0D);
outputStream.write((byte)0x07);
...还是我要离开?
...or am I way off?
很抱歉，如果这真的很基础..在&之前，我从未处理过任何此类东西.几天后我将无法使用该设备.
I'm sorry if this is really basic..I've never dealt with any of this type stuff before & I won't be getting my hands on the device for a few days.
推荐答案
您应该查看串行IP"(SLIP)，并发送不同于IP的数据包类型，请查看SLIPMUX，后者只是一个向后兼容的SLIP扩展.
You should take a look into "Serial Line IP" (SLIP) and to send different packet types than IP have a look at SLIPMUX, the latter is just a backward compatible extension to SLIP.
请参阅:
- 清单: https://tools.ietf.org/html/rfc1055
- SlipMux: https://tools.ietf.org/html /draft-bormann-t2trg-slipmux-00
- Slip: https://tools.ietf.org/html/rfc1055
- SlipMux: https://tools.ietf.org/html/draft-bormann-t2trg-slipmux-00
两者都很容易实现.即使不是Java，我也喜欢链接一个我最近写的实现: https://github.com/Lobaro/slip
Both are very easy to implement. Even it's not Java I like to link one Implementation I recently wrote: https://github.com/Lobaro/slip
