Try the following procedure:
Connect voltage to: =

0 V to radio TXD - pin 2 0 =
V on the computer serial connector pin 3
-------------------------------------------------------------------------=
-------------------------------------------------------------------------=

+5 V to radio TXD - pin 2 +10 V =
on the computer serial connector pin 3

------------
0 V to radio RTS - pin 5 0 =
V on the computer serial connector pin 5
-------------------------------------------------------------------------=

+5 V to radio RTS - pin 5 +10 V =
on the computer serial connector pin 5
-------------------------------------------------------------------------=
-------------------------------------------------------------------------=

-10 V to the computer serial connector pin 2 (TXD) 0 V or short =
RXD-GND on the radio connector pin 3
-------------------------------------------------------------------------=
-------------------------------------------------------------------------=

+10 V to the computer serial connector pin 2 (TXD) +5 V or infinite =
RXD-GND on the radio connector pin 3
-------------------------------------------------------------------------=
-------------------------------------------------------------------------=

-10 V to the computer serial connector pin 4 (RTS) 0 V or short =
CTS-GND on the radio connector pin 4

------------
+10 V to the computer serial connector pin 4 (RTS) +5 V or infinite =
CTS-GND on the radio connector pin 4
-------------------------------------------------------------------------=

This may help you to determine what problem is there (IF or something =
other).
