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

[Howard W. Ashcraft]

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:

1)  Checked the cabling for pin connections, continuity and shorts.  I built another cable, just to check.
2)  Checked all components in the RS232 circuit for correctness.
3)  Checked all solder joints in the RS232 or connecting circuits.
4)  Checked the resistance across the RFChokes for an open connection/broken wire.
5)  Checked the setting for the sidetone to assure it wasn't misset.
6)  Tried using hyperterminal and Elecraft's control software.
7)  Confirmed that the laptop's serial port was available and operating.

Everything else in the K2/100 works fine.

Any suggestions?
