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?

At TRIUMF we use our own version of iocConsole, developed here after
consulting with Eric Norum following his presentation to the EPICS
collaboration. We use the logging capabilities of GNU screen to save
records of all IOC console output. We communicate with the IOCs through
serial-ethernet translators, and use C-Kermit to connect to the
translators' telnet servers. I sense that kermit would be happy to talk
to the /dev/tty devices your Digi port servers provide.
