#
# A wrapper to call the SuperMicro iKVM console bypassing Java browser
# plugins.
#
# Requirements: base64, curl, java
#
# Usage:
#
#   $ ipmikvm-tls2020
#   Usage: ipmikvm-tls2020 [-u ADMIN] [-P ADMIN] IP.ADD.RE.SS
#
#   $ ipmikvm-tls2020 10.11.12.13 -P otherpassword
#   (connects KVM console on IPMI device at 10.11.12.13)
#
# This has been tested with iKVM__V1.69.39.0x0.
