I am using telnet to connect to the LDOM virtual serial console on the SPARC T5. I have also tested nc with the same result. Further tests have also shown that all ncurses applications are affected by this. Running htop inside screen over the serial console on the SPARC T5 also results in garbage. Michael Karcher (CC'ed) has debugged this issue and he says that the problem is that the LDOM serial console is eating away some characters after the "smacs" sequence is sent and "rmacs" is never received, hence the terminal stays in the alternate character set mode. > Is it really vt102-compatible?

So far I have reproduced this issue on the SPARC T5 only and apparently other users of SPARC hardware have seen the problem as well. It can be easily reproduced by running any ncurses application inside screen over the SPARC serial console. I have tried reproducing it on an old SuperH embedded board with a serial console and a Tabor A1222 embedded PowerPC e500v2 board, in both cases the problem was not reproducible. So it seems to be a bug in the firmware of the affected SPARC boxes. Adrian -- .''`.
