Called by a client to make a request from a server. Calling this method causes the server connection's on-execute method to be called (on an event boundary). Returns #t if successful or #f otherwise. The method does not block until the message received by the server, so the return value does not indicate the server's success in handling the message.
These arguments are passed on to the server connection's on-execute method. The size parameter controls the number of characters of data that are sent to the client connection. When size is -1 and format is wx:const-cf-text, the size of data is computed automatically as the length of data.
