<para>Check that the Mercury has been set into remote mode using the SCPI protocol. If it
|
||
still doesn’t talk then the line terminator is probably wrong. Call a SICS developer or
|
||
try to fix it through trial and error by changing the line terminator in the
|
||
/usr/local/sics/sics_config.ini file</para>
