  Just got two T1600s for evaluation.

    1.	The new command set is pretty rational, but you have to play
	tricks to disable ESCAPE (`+'), XON (`^Q') and XOFF (`^S') for
	dial in and hardware flow control purposes.  You have to set the
	ESCAPE (S2), XON (S56) and XOFF (S57) characters to values
	greater than 127 and make sure the control character mask
	(S48) is set to 0 to prevent the control characters from being
	recognized.

	I preferred the old scheme of specifying that the ESCAPE should
	either function as an ESCAPE or simply be treated as any other
	data character.  I also don't understand why the T1600 continues
	to process XON/XOFF when I specify that I want only RTS/CTS
	hardware flow control with no XON/XOFF flow control.

    2.	There is no factory prestored configuration for auto-baud dial
	in applications other than one which sends result codes at the
	DTE!  Sheese!

	Actually I disagree with Cerafin with regard to using the
	prestored configurations.  My inclination is not to bother
	with them and do everything yourself.  You know more about
	your application needs than any number of Telebit engineers
	guessing can.  Besides, it's not that hard.  All the knobs are
	pretty simple to use.

    3.	The T1600 is holding the connection from my new house to our
	T2500 rack!!!!  My T2500 is unable to hold a V.32 connection
	to the same T2500 rack.  Thus, the V.32 implementation in the
	T1600 looks to be better than that in the T2500 already!

  I've talked to Telebit about V.32bis and PEP upgrades to the T1600 and
have been told that they are coming within six months.  No figure on how
much it would cost or if they would charge more for a T1600 with V.32bis
and/or PEP.

  More information later when/if I find anything interesting.
