Hello
On an ARM board we're trying to transmit data with 921600 bauds and we're getting input overruns, and the handshaking line is not set... It's a SA-1100 external UART. I checked - this message comes from drivers/char/n_tty.c: n_tty_receive_overrun(tty); called from n_tty_receive_buf which is a member in struct tty_ldisc tty_ldisc_N_TTY...
Here my quick look stopped - I know nothing about how tty work... Where's the problem? It's 2.4.13-ac5-rmk2 with local modifications... (Trizeps board).
Thanks in advance Guennadi --------------------------------- Guennadi Liakhovetski, Ph.D. DSA Daten- und Systemtechnik GmbH Pascalstr. 28 D-52076 Aachen Germany
