Avanti and AvantiFlex support two default virtual or physical serial ports.  FreeAXP supports two virtual serial ports only.  Virtual serial ports can be accessed using the supplied PuTTY terminal emulator or a commercial terminal emulator such as KEA or Reflection.  Physical serial ports can be assigned to physical COM ports on the host system.

Tip:Migration Specialties recommends enabling both virtual serial ports when building, modifying, or troubleshooting an Avanti configuration.  Having two serial access points to a virtual Alpha system is useful in case one session locks up or network problems block telnet access.
