The TD-32 is delivered with a factory setting for "hardware hand-
shake" with RTS-CTS which means that if only TX, RX and GND
are connected no data will be sent on the receiving modem's RS-232
connection unless RTS is high. The problem can be solved by placing
a jumper between RTS (screw terminal no 6) and for example DSR
(screw terminal no 2) or by disabling the handshake with the command
AT&K0, or with switch 3:2 (switch settings).
