[App_rpt-users] GPIO fan control

I forgot to mention that I've also had good luck assigning multiple Parallel
port pins to PTT in usbradio.conf or simpleusb.conf, such as:
pp3 = ptt
pp4 = ptt
Again, I'd rather not cycle a relay with every PTT. I'd much prefer the fan
run for 2 minutes or so after the last PTT, then shut off. That would save a
lot of wear and tear on the fan and relay.
My setup is probably a bit unusual, as I have several transceivers cooled by
one large fan.
It's occurred to me that I could always build a 555 timer circuit to use
along with my fan control, but a software solution should be just as simple.
I guess I'll have to try to hack the TXFAN script I used on IRLP?
