I'm new to using sockets. I have a very basic client that sends a request, and waits for a response. The response is one stream, but has two parts. The first part is prefixed with ANS and is a set of key/value pairs in this form: KEY:Value with each pair on a separate line.

The second part of the response is prefixed by RCT and this is pre-formatted text that needs to be send directly to a printer.

So what would be the best way to extract both parts of the response, and in the first part, get each Key:Value pair. I might not even need them all, but I have to look at each one to see what the values are then decide what to do with it.

I'm currently writing the response out to a textbox just to understand what its doing, but now I need to actually do something with the data.

Here's a data sample, as it is received:

ANS Result: Data Received                                                                
RCPRES:Q[81]
TML:123
OPP:
MRR:000000999999
<several dozen more KEY:Value pairs>

           <pre-formatted text>
