When replacing a dedicated (dumb) terminal with a PC, TinyTERM version may not connect over the known good serial connection. This usually means you need a null modem adapter on one end of the cable.

On a terminal, the pins line up 2-2 and 3-3. A PC uses the same hardware as the server, rather than the reversed version common to terminals. Thus, the pins need to line up 3-2 and 2-3. A null modem adapter corrects this without requiring a new data cable.
