FYI - from the TCP/IP RT-11 documentation…. NOTE It is possible to install the TCP/IP Package on a 248K machine using the DEUNA/DELUA 18-bit (Non Unibus Map- ping) EU18XM.SYS handler. This handler requires 7.5k bytes for code and packet buffers. This configuration allows at most one networking application to be ac- tive. That plus there is a light version of the FTP user program provided. On the other hand, using a DR11-C, DRV11 etc.. with an external Arduino handling the IP stack would probably be 10x faster (or more) than the native implementation. I only get about 5-8 Kbytes/sec with a DELQA under RT11. Jerry Weiss j...@ieee.org
