I had a similar problem under NetBSD/Mac68k, and I discovered that my modem
was set for XON/XOFF, although the serial connection was configured for
hardware flow control.  I forget what the command was on my modem, but once
I configured it for RTS/CTS (or whatever that is), SL/IP started working
wonderfully.

But then, of course, my problem may have nothing to do with yours...
