One of out customers had a Multi-Tech modem connected to a RealPort 8 device on Solaris 10 server and it was working fine until tuesday morning.
The modem was originally connected to port 1 linked to device /dev/cua/a001 but on tuesday morning activity stopped on modem. I attempted to connect to the modem (tip -9600 /dev/cua/a001) and got the message connected, however i could not process any AT commands to get modems details (i.e. AT&V for modem details).
I asked the customer to connect another port (port 4) and it looked promising as i could process AT commands after tip of /dev/cua/004. When i tried the same thing wednesday morning i could not process any AT commands and nothing was locking the port.
I have since tried multiple ports without success and i'm at a loss as to what could have happened.
Any help would be greatfully appreciated.
