I'm trying to set up an ISP server using, FreeBSD 2.1.5R on a P150 48MB Ram and 2GB IDE HD. I'm using the BB2016 board with external box to connect the (will be?) dial-in modems. I have Motorola 28.8 modems for dial-in. I can connect with the modem in any of the 16 ports of the BB2016 using a terminal comm program, and can type commands and everything on the comm program, but as soon as I begin something that sends a stream of bytes (zmodem file upload or PPP handshaking - slirp, ppp or pppd), the host complains with silo overflows. 1, 2, 4 up to 5 at a time. I'm only using one of the 16 modems at a time (No "production" yet :-( ). I have tried different speeds from 19200 up to 115200 without luck. Also I searched the freebsd lists and found something about changing FIFO_TRIGGER in the sio.c source and I did it. I changed it to 8, 4 and 1, even disabled the FIFO buffers (on the kernel flags for the sio ports) and the result were the same. I got another brand modem (borrowed) and the same happened. I even tried the comm port in the machine but the same happened with it. The modems have CST/RTS flow control enabled. This is done in the the sio?? dev's also by the rc.serial file. The probe messages say that every port has a 16550A, as the one in the serial port of the machine. Any clues? pls. Thanks. -- Samuel E.
