Hi Folk,

Experiences with R3.12.Beta3

1. Time Service Configuration
=============================

 The TS (Time Service) is configuread as in startup script:

	TSdriverDebug=1000
	TSconfigure (1, 10, 60, 0, 0)

result with missing UDP/NTP server:
-----------------------------------
queries UDP/123 (NTP) on host  &  hangs:

../drvTS.c:1607: sednto port 123
../drvTS.c:1622: TSgetData - retry count:

Thats meening: as initiate the TS looking for Unix time useing NTP/UDP
on the boot host. (We have no NTS deamon our boot host but we have 
somewhere else)

HACK:
=====

int /home/epicsSRC/epicsR3.12.DBeta3/base/src/db/drvTS.c, line 709 ff

/*      HACK : herao1   */

#define TS_NTP_HOST     "131.169.112.77"
#ifdef TS_NTP_HOST
        host_addr = TS_NTP_HOST;
#else

 host_addr = bootParms.had; /* bootParms.had = host ethernet address */
#endif

Is any other solution ?

2. SIZE of the iocCore 
=======================

We would like to use mvm162-12 board but  the iocInit faild during 
initialization somewhere the in the memory allocation. (This board 
has 4MB memory) Is there any way to reduce the size of the iocCore ?  
(The drvSup and devSup has been minimalizied!) 

Any suggestion ?
