Hi
I have a piece of hardware connected to te comm port of my computer and I want to read the string that comes from it using hyperterminal. However it seems to be encrypted.  eg it comes out
like

f`x~xxxxxxxxxxxxff`x~xxxxxxxxxxxxff`x~xxxxxxxxxxxxff`x~xxxxxxxxxx
xxff`x~xxxxxxxxxxxxff`x~xxxxxxxxxxxxff`x~xxxxxxxxxxxxff`x~xxxxxxxxxxxxff
`x~xxxxxxxxxxxxff`x~xxxxxxxxxxxxff`x~xxxxxxxxxxxxff`x~xxxxxxxxxxxxff`x
~xxxxxxxxxxxxff`x~xxxxxxxxxxxxff`x~xxxxxxxxxxxxff`x~xxxxxxxxxxxxff`x~xxx
xxxxxxxxxff`x~xxxxxxxxxxxxff`x~xxxxxxxxxxxxff`x~xxxxxxxxxxxxff`x~xxxxxxx
xxxxxff`x~xxxxxxxxxxxxff`x~xxxxxxxxxxxxff`x~xxxxxxxxxxxxff`x~xxxxxxxxxxx
xff`~xxxxxxxxxxxxff`xxxxxxxxxxxxx`~`~~xxxxxxxxxxxx`~`x~xxxxxxxxxxxxff
`x~xxxxxxxxxxxxff`x~xxxxxxxxxxxxff`x~xx

I have messedaround with the settings in hyperterminal and have been told the string is not encrypted coming from the hardware.  Is there some setting in hyperterminal or on my computer which needs to be changed
or is there any other suggestions. I am expecting a numeric data string
eg  ||m00000,00|| or something similar for each receive.

regards
Botch

I'd try a few different settings as to baud rate and also data bits / stop bits. I had similar problems with an old print server (Tektronix), and the gibberish became legible when i hit the right baud rate (which was quite low; 300 or 600). 7 or 8 data bits and 1 stop bit are common settings, combined with no parity. Hope this is of some help. Also, to complicate the picture further, flow control can be set to different methods. Hardware or Xon/xoff can be tried for example.

It actuall worked out as
bits per second=4800 (cause the hardware was at 4800)
data bits=7
Parity=even
stopbits=1
Flow control=Harware
It gve me the string layout I expected
Thanks for your halp
