[Elecraft] K2/100 RS232--No connection between radio and computer.

[Don Wilhelm]

Howard,

There are only 3 RS-232 compatible signals on the K2/100 IO port - be aware
of that when connecting any device.  The RS-232 signals are Transmit Data
(TXD), Receive Data (RXD), and Signal Ground.  Connecting other RS-232
signals to the 9 pin connector on the K2/100 will make 'bad things happen'.

The problem is more likely to be in the computer connection than the K2
port.  The K2 cannot initiate the connection - it can only respond to data
sent from the computer.

Since the port is simplistic, and there are no handshaking signals
implemented in the K2, so be certain your computer or other device is
configured for 4800 baud, 8 data bits, no parity, and handshaking = none.
If your device must use handshaking, be certain you have put the 'optional'
jumper on the end of the cable that connects to the computer which will
provide a path for RTS/CTS (hardware) handshaking.

I can't seem to get the RS232 data port to work on the K2/100.  There is no
communication between the radio and either a computer or my Steppir antenna
controller.  I have:
