/* 8/87 joh Init Release */
|

/* 030791 joh Fixed problem where pend count was decremented */
|
||
/* prior to connecting chan (setting the type). */
|

/* 041591 joh added call to channel exsits routine */
|
||
/* 060491 joh fixed structure pass for SPARC cc */
|
||
/* 060691 joh reworked to remove 4 byte count before each */
|
||
/* macro message */
|
||
/* 071291 joh now claiming channel in use block over TCP so */
|
||
/* problems with duplicate port assigned to */
|
||
/* client after reboot go away */
|
||
/* 072391 joh added event locking for vxWorks */
|

/* 100391 joh added missing ntohs() for the VAX */

/* 031692 joh When bad cmd in message detected disconnect */
