From /usr/include/sys/errno.h: ENXIO 6  No such device or address

which means the system when it came up
did not find a physical device to hook to tty2a.
When the system starts up, is there a line on the start up screen
for each of two serial lines?

File 'tty2a' can exist /dev without the physical device being present.

Check IRQ and/or device address strapping on the com card.
Something is wrong in Hardwareville.
