I am having a problem with the external modem port onthe core I/O board of a K-Class server. The setup involves a bisync modem which is connected to the port (labelled tty0p7) through a cleo convertor box.
The setup was working fine for about a week and a half.
The problem now is that no matter what is sent to the port, the respond is "cannot open port, (DEVICE BUSY), and/or cannot create specified file.
The modem setup guide requires that the port be setup as a terminal and that the getty procees not be running on it (i.e. turn the port off through modifying the inittab file and rebooting).
Is there a possibility that the port gets locked through some sort of a lock file?
All help is greatly appreciated.
Thanks
Karen

Re: Problem with the external modem port on K-Class server. Cannot open port (Device busy)
If it is for remote administration then you should have getty running on it.
Did you try reseting the modem ?

I would try power-cycling the modem, and/or run lsof to see if there is any process holding tty0p7...

Re: Problem with the external modem port on K-Class server. Cannot open port (Device busy)
The setup is actually used for a bisync modem using a Cleo convertor box.
The actual problem was that we needed to unlock the port at the hardware level (Ctrl-B, ur). We had tried all other things, such as removing and re-installing the device,resetting the modem and the convertor box (quite a few times) and even rebooting a few times.
Anyways, the Ctrl-B and ur (to unlock remote port and then using dr to disable remote access) worked fine....just in case someone else has the same issue.
thanks again.
K.
