modification history
--------------------
01e,14jan97,db  added SIO_OPEN and SIO_HUP for modem control(SPR #7637).
01d,24oct95,ms  removed "static __inline__" (SPR #4500)
01c,15jun95,ms  Added SIO_MODE_SET, SIO_MODE_GET, SIO_AVAIL_MODES_GET iotcl's
		Renamed SIO_CHAN to SIO_CHAN
		Changed prototype and name of callbackInstall()
		Added documentation.
01b,22may95,ms  removed unneeded include file.
01a,21feb95,ms  written.
