Experimental Physics and
Industrial Control System

Here at SNS we have lately had problems with IOCs crashing without leaving any trail for analyzing what the problem was.  We have our own home grown procServe and we are looking into the iocConsole/screen software that SLAC is using.  We are different from SLAC in that we use Digi port servers with a driver on one of the linux servers that maps port server ports into local /dev/ttyXXNNN devices.  We just use 'cu' to open a serial port.  IocConsole does not support that but making it do so would not be hard I don't think.

Looks like a modified iocConsole is our best option but before we commit to it we thought we out to see what others are doing to capture the last few lines of terminal activity from running and crashed hard IOCs.

Any ideas?
