Operating Systems Solaris Carrier Detection in Solaris 8 for Dial in and Null Modem Connections Post 302820971 by rstor on Thursday 13th of June 2013 05:44:34 PM

When using the null modem cable on the FreeBSD machine to another computer terminal, I receive the login prompt when the null modem cable is connected, and when I login, and then disconnect the cable and reconnect the cable again I receive the login prompt again. It appears the getty process in FreeBSD is detecting the carrier loss when the cable is disconnected and ending the previous login session. This is the correct behaviour to my understanding.

However on the Solaris system, when the null modem cable is connected to another computer terminal, if I login, and then disconnect the cable and then connect it back again I am still logged in at the shell. This means that on the Solaris machine it did not detect the carrier loss when the null modem cable was disconnected.

Since I have tried the same null modem cable on both the FreeBSD machine and the Solaris machine, I am thinking it has something to do with either a configuration setting in Solaris itself, the hardware on which Solaris is running on, or something else? ....
