Re: [AOLSERVER] problem with Linux telnet and nscp
Darn it. I thought those IAC codes were turned off in the default build. Can someone check nscp.c and maybe ensure a bug is opened on SF about this?

I haven't dug through the code very deeply, but it bears mentioning that I *can* connect to nscp on AOLServer 3.x, even though that version GetLine() contains similar IAC handling code.
