Okay, the only things I see that you have not clarified in your
message is the type of cable (1) it should be a null modem
cable to Com1 connector, which means that the hardware control
signals are connected to each other at pins 4 to 6 and 7 to 8,
by doing so, tx and rx are enabled and not blocked. (2) is the
settings of Hyperterm, it should be set to whatever Com port
that you are physically connected to, with 8N1 and None for
Flow control. If all of that is in place, a power-up on the
TS-7250 board, or pushing the reset button, should allow you
to see the bootup messages.
