How to send LF,CR and EOI in VISA Write function of LabView?

[Noriaki]

I am using LabView 6.0.2 and NI-VISA 2.6 runtime in Windows 95.

I want to change block diagrams of an instrument driver written in GPIB functions into using VISA functions, because I use a HPIB board (HP 83241). The GPIB function in the driver sends command in mode 3 (append CR LF to the string and send EOI with LF). So I think I must send them in VISA Write function, too. But I don't know how to do it. Further, the GPIB Write function sends two strings separated by semicolon. Do I have to send CR, LF and EOI with LF after each string, or not? And how to do?
Although I looked for manuals and help files, I could not find. Please help me.
Thanks.

As far as I know you can set just one termination character for VISA. Therefore it is easier to solve your problem appending "\r\n" to every instrument related command. Don't worry about semicolons if the old program is working with them ... it means that the instrument accepts this kind of command.
Regarding the EOI, I assume (I didn't try it) that you can set it using VISA Advanced > Property > Message Based Settings > Send End Enable. Anyway, make sure that you have set EOI on in MAX.

Hope this helps

You could find a driver for this instrument at http://www.ni.com/devzone/idnet/default.htm . If it's not listed there, it leaves you with one of a couple options. First, I would like you to submit a request for this driver at: http://zone.ni.com/idnet97.nsf/instrumentdriverrequest/
We develop drivers based on demand and popularity so the more requests we have for it, the greater the possibility that we will develop one.
If you would like to try developing your own instrument driver (or modify the existing one), we have documentation, model instrument drivers, and driver templates to help at :
http://www.ni.com/devzone/idnet/development.htm
We also have a syndicate of third party vendors that specialize in National Instruments' products and services. Some of t
he vendors specialize in driver development. I would suggest contacting one of the Alliance members at:
