Try it without the crtscts (actually, use nocrtscts instead of
crtscts).  That will tell us whether it is hardware flow control
causing problems.  IIRC, those mac serial ports didn't have all of
RTS, CTS, CD and DTR, but I don't recall which one(s) were missing.

Also make sure you don't have the xonxoff option.
