We don't use different ports for hardware flow control etc. The general meaning is: ttyd* -- dialin devices open() will complete as soon as carrier arrives, and the port will assigned to the process that holds the device open cua* -- "calling unit" dialout devices; initial open() will succeed immediately without the presence of a carrier, and this will block any partial open() of the according dialin device until the calling unit has been closed again -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
