# Listen on amateur radio aprs-is network for messages and respond to them.
# You must have an amateur radio callsign to use this software. Put your
# callsign in the "USER" variable and update your aprs-is password in "PASS".
# You must also have an imap email account available for polling.
#
# There are additional parameters in the code (sorry), so be sure to set your
# email server, and associated logins, passwords. search for "yourmaildomain",
# "password". Search for "shortcuts" to setup email aliases as well.
#
#
#
# APRS messages:
# l(ocation) = descriptive location of calling station
# w(eather) = temp, (hi/low) forecast, later forecast
# t(ime) = respond with the current time
# f(ortune) = respond with a short fortune
# -email_addr email text = send an email
# -2 = display the last 2 emails received
# p(ing) = respond with Pong!/time
# anything else = respond with usage
#
# Meanwhile this code will monitor an imap mailbox and forward email
# to your BASECALLSIGN.
