Specifically by taking remote command as an example, test content and result are described:
Serial ports is connected on the STA that TEI is 2, order is inputted in serial ports software:
$ version
As a result it exports:
===================================
Software : v1028
Build time : 2018-11-14
===================================
Remote command content is sent on the debugging software of operating terminal are as follows:
hpav cmd -tei=2 -cmd="version"
Indicate " version " command information for the sta that inquiry tei is 2.
It returns the result are as follows:
comand result from tei=2 seq=9:
===================================
Software : v1028
Build time : 2018-11-14
===================================
Indicate that the STA for being 2 from tei returns the result information.
Effect is the same with serial ports input version order output result is connected on the sta that tei is 2.
Further, it is not returned the result if sending above-mentioned remote command, can determine whether access device and TEI is 2 Between STA may communication efficiency is bad or TEI is 2 equipment there is no etc. reasons.
The present embodiment core concept is to construct Debugging message in operating terminal by a kind of method of virtual serial port, by Debugging message is sent the purpose equipment in carrier network by access device, and purpose equipment is handled again after receiving Debugging message And response.Site operation personnel is set to carry out debugging to carrier network from operating terminal in the case where not unpacking and examine automatically It is disconnected, it is more easy-to-use and safe, greatly promote O&M efficiency.
