If IPACP is taking a lot of time you dont have the modifications for NNTP_TCPCMU that I submitted to Geoff. They should be in 5.9B. I allready noticed the trouble in the spring but had didn't have the time to make the modifications befor this fall. That trouble was that write_net (used to write data tothe socket) wrote every single output line out with the PUSH bit set so IPACP sent a line in one packet. I rewrote write_net to buffer the data. i thin this should be done also in the other TCP/IP implementations and also on the dcnet channel.
