Hi Emma,

Does your Moxa run on Linux or Windows? Mine is Linux and I use the local program /bin/setinterface to select the mode (RS232, RS482 2 wire, RS422, RS485 4 wire).

When running EPICS on the Moxa, you can do this from the EPICS startup script with the 'system' command (3.14.12) or from inside StreamDevice with the 'exec' command.

Hi all,

We have recently been investigating options for controlling serial
devices via a terminal server.  We particularly want the ability to
software switch between RS-232/RS-422/RS-485.  One that has this
capability and seems to be generally recommended by the EPICS community
is the MOXA NP6650 32-port device server.

However, after buying one to evaluate, we discovered an annoying
'feature': to change the settings of a serial port over the web
interface (baud rate etc) requires a reboot of the server, which of
course disrupts communications on all ports (and actually crashes my
soft IOC, though this might be a streamDevice issue...).

We wondered if anybody else has also come across this problem?  If so
have you found a way of getting around it, or do you have any other
recommendations?  I have contacted MOXA technical support about the
issue, but they don't seem prepared to fix it.

Thanks in advance,
Emma
