I want to use the modems in our 1800 to support dial *out* uucp traffic. We are *not* an ISP. Our traffic is almost entirely outgoing. I have tried a number of methods to access the modems. 1. GNU/Taylor uucp has built in support to use telnet to access modems in a terminal server (I am using the 'i' protocol, but 'g' and 'G' have been used too). 2. nd/tcpcon creates /dev/pty's that connect to tcp ports on a remote host. 3. rtty does the same thing, but is a little cleaner. CU works great, but uucico has trouble. It looks to me like the data path to the modems is not 8 bit clean, (but it could be a handshaking problem). I can use a command like 'cu -l /dev/ttyrf' and the process rtty will open a tcp connection to port 5000 on the 1800. All traffic in both directions flows through this rtty's connection. Works like a charm! But uucico chokes. I can pass about 8 or 9 k of 7bit ascii through a uucico connection. But if the remote file is any larger, the connection chokes on a lot of checksum errors. If there is less than about 8k, there are zero checksum errors. This suggests a handshaking problem. If there is *any* size of 8 bit data (ie. a gzip'd file), then nothing gets through. Check sum errors happen on the first packet. This suggests the connection is not 8bit clean. One other terminal server manufacturer (I forget who, might be computone, or maybe digi?) has two ranges of telnet ports that is used to get around this problem. The second range is used when you want a "raw" (I guess this means 8 bit clean) tcp connection. To connect to the 1800's modems, I am using port 5000. Keep in mind, this is dial "out" that I am trying to do. I don't think the TServ parameters apply to these connections, but just in case, I set telnet mode=binary, and buffer characters=no. I posted a similiar question a couple of weeks ago, and although a couple of fellows tried to help, it turned out (after a bit of email exchange), their systems only did dial *in* uucp. My 1800 is running 5.0Ap36. The Unix system is a Sparc 20, Solaris 2.5. Any suggestions would be greatly appreciated.
