    83833) Type 'tftp<CR>'
     84   This forces the network link to half-duplex.  If your network link is
     85   locked at full duplex you'll have to find another port!
     86   The RTEMS network driver can be forced to 100 Mbs/full-duplex by setting
     87   the bootstrap environment variable IPADDR0_100FULL to Y.
