The NEC PC-8300 has support for the optional internal modem, and due to this, the STAT has extra parameters that have to be specified.
Add "P1O" on the end of your setting. That is a P, then a 1, and then the letter O. Alternatively you can just keep the PC-8300 in 8201 mode and continue to use the old settings with an OUT 163,2 from BASIC.
