35 Input and output work as for subprocesses; `delete-process' closes it.
36 Args are NAME BUFFER HOST SERVICE.
37 NAME is name for process. It is modified if necessary to make it unique.
38 BUFFER is the buffer (or buffer-name) to associate with the process.
39 Process output goes at end of that buffer, unless you specify
40 an output stream or filter function to handle the output.
41 BUFFER may be also nil, meaning that this process is not associated
42 with any buffer
43 Third arg is name of the host to connect to, or its IP address.
