Hi

We managed to connect and control a serial device using Portserver 4 MEI.  
The problem is that after disconnecting and reconnecting the serial cable, the serial device is not reconnected and we need to reboot Portserver 4 MEI.

Thank you

More information is needed.

\*What cabling pin-outs are used?  
\*What are you connecting to the serial port and is it DCD sensitive?  
\*What port profile is used?  
\*What flow control method is used?  
\*What port signals are seen as active during the connection and during the re-connection (this can be displayed under the web interface: Device Information \> Serial Ports & Diagnostics)?  
\*Is the RealPort driver being used? If so, what operating system and version?
