  state: Exp;  lines added/del: 2/2
modified VADIC and VA212 to attempt the call TRYCALLS times, instead
of the previous 5 times.
----------------------------
version 1.5        
date: 84/04/10 15:25:11;  author: joe;  state: Exp;  lines added/del: 30/7
Modified va811 code to retry call up to TRYCALLS times.
----------------------------
version 1.4        
date: 84/04/10 14:56:50;  author: joe;  state: Exp;  lines added/del: 104/1
added code for VA811S.  Copied most of VADIC code, but this is a 
single line dialer, so no MACS support.  Also modified the micom
stuff to match FLUKE's Micom prompts.  va811 tested, micom not tested.
----------------------------
version 1.3        
date: 84/02/20 09:20:52;  author: joe;  state: Exp;  lines added/del: 141/0
Added code for VA212.  Similar to VADIC 3451, but differs in modem
responses.  Tested and verified.
----------------------------
version 1.2        
date: 84/02/20 08:03:55;  author: joe;  state: Exp;  lines added/del: 3/1
Added more info on error returns from vaopen().
----------------------------
version 1.1        
date: 84/01/24 11:19:57;  author: lcp;  state: Exp;
