problem in communicating to the gpib device with asyn4-6

[zhangdemin99 <zhangdemin99@163.com>]

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".
