INTERLNK/INTERSVR

[Dwight K. Elvey]

Hi
 I've cracked other protocols by connecting another
computer up to monitor the traffic on the serial lines.
I don't think they did anything fancy. Probably the toughest
thing might be determining the CRC,ECC or checksum method
that they use. It would be best if you could simultaneously
monitor both directions with two serial ports but
I just did one direction at a time and then experimented
until I got all the handshake.
 You, of course only want to use the input of the monitoring
computer. You could make a snooping connector or as I did.
I just used two easy clips on the exposed connector.
