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.
