RCX IR Tower communication failure

All,
I have a RIS 1.5 set installed on windows 98 PC . I have got some
trouble with IR Tower and RCX communication . First the IR tower was
not detected : using the bios setup menu from start up I succeeded in
setting correctly the serial COM2 (disabling COM1 & LPT ports).
It was working fine : I downloaded firmware and a short program. But
now it doesnot work : the IR tower is detected and looks fine but does
not communicate to the RCX . Here is the log file I got after testing
the IR tower and RCX brick:

There is something wrong with the RCX. I made myself the serial cable
according to information got from RCX internals pages. I am afraid the
IR tower has been damaged !!
Anybody to help me ?
Thanks a lot

Re: RCX IR Tower communication failure
I hate to ask you this, but how is the 9 volt battery in the tower? Is the
light turning on when your attempting to transmit?

Re: RCX IR Tower communication failure
... the battery is new ! I made another test and I realized the cable
was not safe (wrong contact between pins and wires, I think) that can
explain the wrong communication. I have to check the connector
welding...hoping the IR tower is not damaged

Re: RCX IR Tower communication failure
I could make a pin to pin drawing if you need it. Seems that a wire may have
come loose to cause this problem. Let me know if you need any information.

http://graphics.stanford.edu/~kekoa/rcx/ ) :
Pin To Name Description
2 3 RD Receive Data
3 2 TD Transmit Data
5 5 SG Signal Ground
7 8 RTS Ready To Send
8 7 CTS Clear To Send
Pin 4 connects to pin 4 but is unused; pins 1, 6, and 9 have no
connection.
is it right ?
I used HyperTerminal to test the IR tower : if works fine but I don't
see the led lighting (according to the lego mindstorm trouble shooting
guide, it shoud light while typing !).

Plugged in my old serial tower and loaded up the RCX. The green light is on
with every download and communication from the tower to the RCX. I tested my
factory cable and the connections are as you described.
I would try reloading the firmware. Take the batteries out of the RCX and
turn it on to clear any information. Watch your tower when you try to
reload. If you have no green light under the IR windows you have a power
problem. I have had a similar problem with a marginal battery and I would
test it or change it to be sure it is OK.

Re: RCX IR Tower communication failure
the IR tower and removed the back . I used hyperTerminal to test the
connection to the tower : by pressing the battery , it was working fine
and the green led lighted !
Thanks for your help
