B>experiences in dealing with Tandy in the last few years, was told by

From the technical reference for the Model II, (yes, the pinout for the
Model II/12/16/16B/6000 is the same for channels A & B):

	Model II/12/16	       Attached Device
	Frame Ground    <-> 1
	Transmit Data   --> 2
	Receive Data    <-- 3	 This is a standard DTE configuration
	Request To Send --> 4
	Clear To Send   <-- 5
	DataSet Ready   <-- 6
	Signal Ground   <-> 7
	Carrier Detect  <-- 8
	Data Term Rdy   --> 20

	Xmit S.E.T      <-- 15  Not available by default
	Xmit Clock      --> 24  Not available by default
	Receiver Clock  <-- 17  Not available by default

This does not apply to the multiterminal ports which are a botched DCE 
configuration.

<Radio Shack is bound to support most of this;  it is an EIA standard.
 Funny...  They will support a connector, but not the machine it is 
 bolted to...>
