* SMC1 serial port blocks

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.
