C4 Manual Rev 7.5.2
1.5.18 Remote Mode EIA-232 Port Initialization
The CC-3 required that to use the EIA-232 port, the port had to be initialized by
switching the mode switch to SETUP before switching to REMOTE mode. The C4
eliminates this requirement. The EIA-232 port is initialized each time the remote
switch is switched to REMOTE mode.
1.5.19 Remote Mode Fault Tolerant Parser
The C4 uses a very fault tolerant parser. Command strings received over either
the EIA-232 or GPIB ports are converted to upper case, extra spaces and tabs are
removed, commas are converted to spaces and line terminators are corrected if
necessary. For this reason, programs that work properly with the C4 and not with
a CC-3, that use only CC-3 commands, probably have syntax errors that the C4
parser corrects. See Section 9.7.7
