Did you test that using minicom with 115200 Baud, 8N1?

I'm just guessing, but try to look at src/mainboard/via/epia-m/*.lb
and src/superio/via/vt1211/vt1211.c. Either LinuxBIOS is simply not
configured to enable ttyS1, or the code isn't there or incomplete or
wrong (?)

Maybe it's even simpler? Did you attach the cable to the correct port?
Did you configure minicom to use ttyS1 instead of ttyS0? Etc. etc.
