RE: Capturing data from string which is sent by device

[Mark Rivers <rivers@cars.uchicago.edu>]

Hi Pilkyu,

I have read the manual for the MPC that you sent.  Indeed it should never sent the unprintable characters like \377\372.  I see that you are using a TCP connection to the MPC, which means you are using its internal Lantronix terminal server.  I think you may have some setting on the Lantronix wrong, for example the start bits, stop bits, or parity.  Can you open a Web page to the Lantronix and see what settings you are using?

Since you have already built the ip application you could try simply using the devMPC device support and see if that works.

To test, comment out the StreamDevice support and add this line to your startup script:

dbLoadRecords("$(IP)/ipApp/Db/MPC.db","P=10MeV:,PUMP=TM:,PORT=P1,PA=5,PN=1")

Your application must have been built using ipSupport.dbd and ip.lib.

Note also that you have an error in your startup script.  You need to define the macro parameter S

dbLoadRecords("db/devvacuum.db","P=10MeV:,R=TM:,PORT1 =P1 ,A=1")

filename="../dbLexRoutines.c" line number=321

Bad character '$' in record name "10MeV:$(S,undefined):message"

Hi, Mark

Here is complete communication with the controller, including both what 
is sent as well as what is received.

As you said, this sentence "\377\372,j`\377\360" is meaning something 
wrong while communicate between device and me.

I don't know why I received that line which I didn't want. and I watched 
a manual for searching about that number, the manual says nothing for 
that number. I attached the manual. While I am writing this mail, I saw 
some of strange things in my files. but I can't find and fix it.. Could 
you give me a favor? I hope remove "��,j`��". Thank you.

P.S. If I want to know about function of "@mismatch" where I can find 
direction or example?

Pilkyu Jung
