Dear EPICS Colleagues.

It is Suk Choi from RISP.

I am testing Leybold TD20 Classic Turbo pump controller..

It uses USS protocol.

I sent a message like next line.

out 0x02 0x16 0x00 0x10 0x17 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x10;

At EPICS IOC represented like

epics> 2016/08/12 10:36:11.504 /dev/ttyr30 write 24

\002\026\000\020\027\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\020

I don't know why 0x16 changed to \026 ...

Hexa number 10 chenaged to hexa number 20 ....

I want to know why it works like that...

And how do I send a message to get  right response  from TD20 classic TMP controller...?

Here is asynSet options.... and EPICS IOC response...
