Title: Re: Serial port access and loging services for IOCs?

David, 
Many Digi port servers allow the definition of a cache/log for each channel on the port server itself.  I found this feature when I updated the firmware.  It was nice to capture the last lines (~ max 512kb) of terminal output when all the other systems failed.

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.
