	<*> Yes, the rate is accurate. Whats also funny is the shorter

	    of the calc. it makes. The control files are really strange,
	    sometimes 9000bytes/sec :-))).

	<*> Yes, and larger. Using v42bis compressed, even compressed files
	    come over faster then using 'g' without compression.

	<*> ',eg' is used (Thanks to Bruce!) to try 'e' protocol first. IF
	    The host site doesn't have 'e' then it will still use 'g'. If
	    you just use ',e' then it looks for 'e' only.
