streamDevice2(stringin) problem!

[黄一鸣 <huangym@ihep.ac.cn>]

Hello
    I have a problem in streamDevice2.
    I use the streamDevice to control a VME monitor. As the example in streamApp,I have three files: vme.cmd, 
vme.db,vme.proto.These are parts of them:
-------------------------------------------------------------------
       vme.cmd
!./streamApp

dbLoadDatabase "O.Common/streamApp.dbd"
streamApp_registerRecordDeviceDriver

#where can protocols be located?
epicsEnvSet "STREAM_PROTOCOL_PATH", ".:protocols:../protocols/"

#setup the busses

#example serial port setup
drvAsynSerialPortConfigure "COM1", "/dev/ttyS0"
asynOctetSetInputEos "COM1",0,"\r\n"
asynOctetSetOutputEos "COM1",0,"\r\n"
asynSetOption ("COM1", 0, "baud", "9600")
asynSetOption ("COM1", 0, "bits", "8")
asynSetOption ("COM1", 0, "parity", "none")
asynSetOption ("COM1", 0, "stop", "1")
asynSetOption ("COM1", 0, "clocal", "Y")
asynSetOption ("COM1", 0, "crtscts", "N")

dbLoadRecords "vme.db","PREFIX=VME"
#dbLoadRecords "scalcout.db","PREFIX=DZ"

iocInit

#enable debug output
var streamDebug 1
-------------------------------------------------
      vme.db
record(stringin, "$(PREFIX):T2") {
  field(DTYP, "stream")
  field(INP, "@vme1.proto spyT2 COM1")
  field (SCAN, "I/O Intr")
}
record(stringin, "$(PREFIX):T3") {
  field(DTYP, "stream")
  field(INP, "@vme1.proto spyT3 COM1")
  field (SCAN, "I/O Intr")
}
.......
-----------------------------------------------------
     vme.proto
Terminator =" ";
ReplyTimeout = 10000; # 10 sec is very long, for keyboard input
ReadTimeout = 2500;   # also long for keyboard input

spyT2{
   in "T2:%2c";
}

spyT3 {
   in "T3:%2c";
}
.......
------------------------------------------------------------
     Last month,it works well, I can get the value from the VME monitor with it.
Recently,I install CSS_EPICS_2.3.0-boy, I want to desire a manager display for it.
But the problem happened.This is the error :
-------------------------------------------------------------
#dbLoadRecords "scalcout.db","PREFIX=DZ"

    It works bad ,I don't know why this happen.I run "example.cmd","test.cmd",they have the
same problem.Interesting,only "stringin" record performs error,others run well. 
    Please help me,looking forward to your reply.
