I presume that you are using devGpib and ASYN. I think that the
following command table entry will do what you want:
{&DSET_SO,GPIBWRITE,IB_Q_HIGH,NULL,"DISP:TEXT '%s'",200,NULL,
0,0,NULL,NULL,NULL},
Then in your st.cmd file you would have lines like:
asynOctetSetInputEos("L0",0,"\n")
asynOctetSetOutputEos("L0",0,"\n")
If you want to include a single quote character in the displayed
message you must send it as two adjacent single quote characters, or
you can change the command above to

{&DSET_SO,GPIBWRITE,IB_Q_HIGH,NULL,"DISP:TEXT \"%s\"",200,NULL,
0,0,NULL,NULL,NULL},

(then you'll have to send a double quote twice to get it into the
displayed message......)

Dear all,

I am using ASYN to communicate the GPIB device, and a serial line
directly attached to the IOC. I want to send a string command to
the GPIB device, such as "DISPlay:TEXT" ,and the text which I want
to send is anystring, then how to creat the command array entries
when creating ? the "eos" is "LF".

Many thanks in advance.
