When I try to connect a serial I/O card called Digiboard with a modem
TELEBIT T2000 using the tip command, the following error message is
displayed on the console.

c8[0] line 0: unexpected receive interrupt

It is possible to send data through modem but nothing is echoed back
from the modem to terminal.

I'm using MIPS M120 and RISC/os 4.50, and set jumpers, connectors and
switches on the card by the Serial I/O Board Configuration Manual.

Would anyone tell me what is wrong?
