I have two identical linux boxes connected via a serial link (9600
bit/s without any handshaking). In both boxes the serial port is
realized by SMC1. One box is receiving and the other transmits a long
stream of bytes. If I start the receiver after the transmitter, it
seems that the transmitter cannot send anymore, even when I start the
receiver. The transmitter has to be restarted to solve the problem.
Any help is appreciated,
Anna

Are you really sure, you don't use handshaking? You could try to connect
your boxes via three signal lines only: RxD, TxD and GND. This should
ensure that no (hardware) handshaking is involved.
