#
# Expects the following environment variables to be set:
# XBUS_NAME - bus name
# UNIT_NUMBER - xpd unit number
# UNIT_SUBUNITS - number of subunits in this xpd
# UNIT_TYPE - xpd type number (from protocol reply):
# 1 - FXS
# 2 - FXO
# 3 - BRI
# 4 - PRI
# XBUS_REVISION - xbus revision number
# XBUS_CONNECTOR - xbus connector string

#
# Output data format:
# - An optional comment start with ';' or '#' until the end of line
# - Optional Blank lines are ignored
# - Fields are whitespace separated (spaces or tabs)
#
# The fields are (in command line order):
# 1. CHIP select in decimal (ignored, taken from 3 LSB's of subunit number)
# 2. Command word:
# - RD Read Direct register.
# - WD Write Direct register.
# 3. Register number in hexadecimal.
# 5. Data byte in hexadecimal. (for WD command only).
