You should make the following hardware settings before installing the PC-HSICA
card in your computer.

As shown in Fig. 1, Pin 20 of the PC-HSICA's RS-232-C Interface Connector may
function either as a DTR (Data Terminal Ready) output or as an RTS (Ready to
Send) output. Which of these two functions you assign to this interface line will
depend on the handshake set stipulated by your driver software (i.e., CTS/DTR or
CTS/RTS).
