>I am not up to speed on all the meanings behind some of the telco terminology so when I look at the equipment that is available now I can t find something that simply allows me to plug in my telco line then pass it on to the modem.  Or lets me tap into my RS232 line and displays the data.  There is a lot of fancy equipment that is designed for T1, DSL, etc& but I can t seem to figure out if it will do something this simple.

AFAIK, there isn't any such beast.

Are you sure you mean 202 as opposed to 212?
202 is FSK, for four wire interfaces.
212 is phase modulated, for dialup use.


I did a box for 212 years ago, using a pair of modem chips and an inductive coupling for debugging point of sale terminals.
