I'm having some problems with this setup: 1> Sometimes, when someone hangs up, the modem is left in such a state that it will not answer the phone until it is power-cycled. The RD (rcv data) and SD (send data) lights remain on and the modem will not answer the phone. 2> Many times, output gets garbled, especially right before a read operation. I have heard that the I/O chips on this board can be replaced by more "intelligent" chips. Is this the case, and if so, what is the part number of the intelligent chip. On a related topic, is there anyway to flush typeahead in Xenix?? I am using the Xenix equivalent of cbreak() (by setting various flags with ioctl()). fflush(stdin) doesn't seem to work, although it doesn't return an error code.
