Dear net, I have upgraded my ZyXEL Elite modem to ISDN. Since then I have been having intermittent problems with uucp sessions: sometimes packets arrive with bad checksums or out of order. Sometimes whole sessions go without any problem. I only see this problem with high-speed ISDN connections. There are no problems with V34 (max 28.8k) connections. It looks like a handshake problem, but it isn't. I have checked both the lights on the front panel of the modem, and with a small rs232 tester. RTS goes off and on. The modem is configured for rts/cts handshaking. I am using the i protocol with default 1024/16 windows. There are no sio overflow errors in the console. I am running freebsd 2.2 gamma up to ctm 148. The machine has a Pentium 166 on a Gigabyte 586DX motherboard, and I am using the built-in serial ports. (cuaa0 in this case.) I have set up /etc/rc.serial to init port 0 as a modem port. Port speed is set to 115200. The ZyXEL's firmware is v2.04. When I try to ftp a large file, using ppp over this same modem, and to the same provider, I get no errors. (At least, the transfer rate is what it should be, and netstat -i shows no errors.) Any ideas? Thanks, Ben
