how to read specific bytes in rs232 buffer

[fabe]

Hello Guys

I trying to pull out data from RS232 but i only need to read a specific character. Example :

Read buffers:

level -2.32 locked on

ok*

From that read buffer, all i want to extract is the -2.32. Any ideas? Please give an example.

Thanks

Use the match string function to search for "level" and then use the scan from string for a float.
Using the scan from string directly probably is too difficult to keep correct.
