Assuming that the missing space /sbin/agetty/dev/ttyS2 is not real, otherwise you have serious issues. It's likely that you haven't asked agetty to monitor Data Carrier Detect. When asserted DCD means that there is a session in progress. DCD in turn requires DTR to be present, as Data Terminal Ready when asserted means that the other RS-232 lines from the ...

According to something I read here it may be there are some compile-time options in the kernel for disabling newly created pty locking, but I didn't want to do that. So, I did ...
