Please tell us your machine and compiler when making net requests like this.
The answer differs depending on whether the environment is a PC (and upon the
PC compiler), System V, Berserkely Unix, VMS, IBM/CMS, etc.  Stuff having to
do with single key strokes is system dependent and may require special
terminal setups and/or exotic I/O calls and/or etc.
