- The source of the BSD telnet seems to be available on a number of
- anonymous ftp sites so if you're running on a Sun then this may help.
- Use archie to look for telnet.c.
- Meanwhile, I'm looking for something similar for HP-UX, i.e. a telnet
- which disallows shell escapes (I'm not bothered about trapping errors).
