in thread What is the best way to master perl

A trip down memory lane here:

Closest I ever came to writing a driver in Perl was a while back when I used to use a EPROM burner that I got for free that didn't have the user software to go with it. I obtained a photocopy-of-a-photocopy-of-a-... you get the idea of the user's manual and it had the command protocol documented in its appendix.

I wrote a UI of my own using Perl running on top of a pre-cursor to Cygwin on DOS and wrote a XS module to actually talk to the serial port on the burner. The Perl program used the XS module for the low level stuff passing commands and data to the XS module's methods and happily burning on to the EPROMs or dumping them or whatever I needed.

Don't really use EPROMs any more and I gave the burner away along with the XT that I used to drive it. Getting XS to work was an education to say the least.

    ... and that was back when we were making our own EPROMS
        with a broken exacto knife, a pair of waterpump pliers and a band saw!

    ...and going to and from school required a 9-mile walk thru 6-foot (2m) snowdrifts, going uphill both ways!


      :-) but ++blue's memory-lane-byway. XS still isn't for the fainhearted.

          with a broken exacto knife,

      You had a broken xacto knife to work with? We'd have killed for one of those... we had to start with iron ore! :-D
