If the process consists only of sending one line at a time, you may use FGET(). This doesn't require a length parameter. It will take one line at a time. However, this does not add the carriage return.

So, using either that approach of FREAD(), you may have to either add a carriage return or to extend it to 129 bytes.

But, then again, it's not clear if the problem is local or on the server. Where is it? Have you identified if the problem is not sending the proper string or if the server receives it ok but it's within the interpretation that the problem is?

It seems here you're using a Web Service for a socket type communication. Is that what you are trying to achieve?
