The method receives the first part of response message from the server up to maxbytes bytes . Use getresp_hasmore and getresp_next to get getresp_rest to get the remaining part of messages . When the server sends the message using ENDM the string returned may be longer than maxbytes but only till the first line after that . When maxbytes is 0 the procedure reads the first line .
