Hello people, I'm at my wit's end! I've got one more problem I need help with (hopefully the last). I've set up UUCP to a linux machine, and I'm finding that uucico fails miserably due to too many checksum errors. I've tried protocols i and g, and they both suffer from the same problem. I've made sure that XON/XOFF flow control was off, and that CTS/RTS flow control was on. I did this by checking stty on my /dev/cua* device, which listed "-ixon -ixoff crtscts". I also send a command to my modem when dialling that explicitly sets CTS/RTS flow control on, and XON/XOFF flow control off. I've tried varying the packet size and window size, but I still find the same problem. I've also varied the DTE baud rate with no success. I used to run linux UUCP to this same site without any problems, and with the same protocol, packet size and window size that FreeBSD is trying now. I never used to get bad checksums. The end result is that I can only transfer a few hundred, or thousand bytes before uucico gives up altogether. Linux used to give me around 1300 bytes/sec, whereas with FreeBSD I'm getting a dismal 150 bytes/sec because of all the errors. If this is any help, I turned the uucico debugging on, and the Debug file was left full of bad checksum messages. It also listed the data it received at each step, and I found that there were bytes missing from the stream... I could tell because mail is usually sent as plain text, and I could see that with a packet size of 64 around 10 bytes go missing, and the next packet header is mistakenly taken to be data. I've no idea how this comes about. Please help! Raoul
