930  Displaying Communications Configuration Status 
Some communications configuration data can be changed 
by 
the SETCOMM procedure or by the 
ALTERCOM procedure under SSP.  These changes can affect the way communications jobs run.  You can 
verify the configuration status 
of 
each communications line using the STATUS 
COMCNFIG 
and STATUS 
COMM procedures. 
The SETCOMM and ALTERCOM procedures are described as follows: 
•  SETCOMM:  The SETCOMM procedure under SSP changes some communications parameters in the 
system configuration record.  An initial program load (IPL) must be  performed before the changes take 
effect. The changes are permanent. 
You can use  the STATUS 
COMCNFIG 
(D H) command to display the present settings. 
•  ALTERCOM:  The ALTERCOM procedure under SSP changes some items associated with batch BSC, 
SDLC, or a communications line.  ALTERCOM changes information only for the display station 
at 
which it 
is 
run. 
If 
ALTERCOM 
is 
run while an SSP-ICF (interactive communications feature) subsystem 
or batch 
BSC 
job 
is running, 
it 
will 
have no effect on the 
job 
that 
is 
running.  Changes made using 
ALTERCOM remain in effect until the AL TERCOM procedure 
is 
run again, 
or 
until the SETCOMM 
procedure 
is 
run. 
You can 
use 
the STATUS COMM (D C) command to display the present settings. 
Use the help menus or 
see 
the System Reference manual for additional information on these procedures.
