Do you have TCP extensions turned on? If so, in /etc/sysconfig, alter the following lines: tcp_extensions=YES to be: tcp_extensions=NO The problem is that some terminal servers and/or routers barf when they see packets with TCP extensions turned on (despite the fact that they are an internet standard). You should probably turn them off for modem use anyhow, as they make the TCP headers bigger. Gary -- Gary Palmer FreeBSD Core Team Member FreeBSD: Turning PC's into workstations.
