Hi Marty, Jeff et al
When asynOctet->read() (or at least readRaw() of the TCP port driver) is
called on vxWorks with pasynUser->timeout < 1/sysClkRateGet() [normally
about 16 ms], the read call hangs and does never time out.
I think it is actually a problem with epicsTimer, which never expires
for timeouts < 1/sysClkRateGet(). But I have not tested this.
I think, a timer should wait at least the specified amount of time, thus
always round up to at least one tick.
