# Connection script for SLIP from east.alma-ata.su to itpm.alma-ata.su
#
# This script calls to two different phones on the same machine
# On first and second pass we calls PHONE1, on third - PHONE2.
# If we connected at some phone, next try to connect starts with
# this phone number.

# By Paul Cadach (Alma-Ata)
#
# note, that some of the features used in this script, are
# deemed dangerous security-wise by me (Uri) and are thus
# disabled in the DIP code. In order to enable them, look
# through the source, mainly of "command.c"...
