13.17 The DB9 Console Adapter
Some Personal Computers use a 9 pin DB9 interface for serial communications. The
terminal emulation programs may require certain lead status. Since console connections
are generally implemented as three wire interfaces (i.e. RxD, TxD, and SG); this may
pose a problem for the terminal emulation programs.
Below is depicted the wiring of a DB9 adapter which eliminates the problems associated
with these terminal emulation programs. It is used with a standard straight category 5
RJ45 cable.
