dear Norum,
Tanks for your reply.
I have set like what you suggested:
{&DSET_SO,GPIBWRITE,IB_Q_LOW,NULL,"DISP:TEXT \"%s\"",0,200,NULL,
0,0,NULL,NULL,NULL}
{&DSET_SI,GPIBREAD,IB_Q_LOW,"DISP:TEXT?","%39[^\r\n]",0,200,NULL,
0,0,NULL,NULL,NULL}
asynOctetSetInputEos("L0",-1,"\LF")
asynOctetSetOutputEos("L0",-1,"\LF")
but there are also some problems:
epics>2007/08/04 10:18:38.879 /dev/ttyS0 write 18
DISP:TEXT \"abcd\"L
epics>2007/08/04 10:18:45.263 /dev/ttyS0 write 11
DISP:TEXT?L
2007/08/02 10:18:50.266 display-query read status ""nin 0
2007/08/02 10:18:50.266 display-query error.
At the same time ,thanks Mayssat for your suggestion.
I am sure the message terminators for the device are"LF".
I think that there may be a language problem here. It is quite
likely that the terminator for your device is a single <linefeed>
character. The documentation probably refers to this as LF and you
are making the assumption that the terminator is literally 'LF'.
Try changing the end-of-string commands to the following and see what
happens:
asynOctetSetInputEos("L0",-1,"\n")
asynOctetSetOutputEos("L0",-1,"\n")
