Does anyone have any experiance interfacing a M100 to a digital signal ( i.e. TTL). What I need to do is interface a pulse generator to the M100 and record the time at which each pulse occurs. I do have the abilty to tailor the pulses. But would appreciate any suggestions on how to hardware interface and also how to fetch the occurance from the port used. I have also considered using a hardware interrupt to trigger the execution of a basic routine to record the current time??? Thanks, I appreciate any thoughts anyone may have on this.

Paul, I know very little about the barcode port, but I have read that some have used it for input of digital signals (on-off, 0-1), for external device monitoring. Obviously, there is some port # that you can read to find out what is going on there. An apparent advantage is that the port already has an input plug, all ready for use. Perhaps some of the technikos can fill you in on this, or give you some more concrete ideas. *** There is a reply: 85651 Enter command, N for next message or <ENTER> for menu:n

Tony, That is one of the primary ports that I am considering. However I too know very little about the numbering of this port and also the conditions for which you can read an input from it. Me thinks. Thanks for the reply, I guess we'll just have to wait and see if anyone can come up with anything. I wait with baited computer. Paul. P.S. thanks for the reply!!
