- When I was down in GA I had trouble with lots of busy signals and wrote a
- program called SPOLL which controls UUCICO. Some of its features were the
- ability to time a polling sessiong. For instance if UUCICO got a busy signal
- the my program would keep trying for a specified time limit or specified
- number of tries. I use it all the time on my system and I distributed it
- a bit through email and I think I posted it to c.b.w, but I dont remember
- right off. Due to an error on a non-backed up drive the source code to the
- most recent version was lost, :( so I have some rewriting to do, and I need
- to fix a bug that appears when you try to poll more than one system at a
- time from one SPOLL session.
-
- SPOLL -delay=15 -time=5 \-t 70 -s SYSTEM
-
- Tries for 5 minutes to connect to SYSTEM, delaying 15 seconds between each
- UUCICO attempt. -t 70 -s SYSTEM is passed to UUCICO so that uucico is run
- as UUCICO -t 70 -s SYSTEM.
