[comp.dcom.modems] Serial Ports

evanc@isishq.fidonet.org (Evan Champion) (04/01/91)

I am currently thinking about what I want to put in to my new computer 
(which I will probably be getting this summer.)  I am sure I want a 16550A, 
but is this the latest/best chip available?  I also know about the Hayes ESP 
board, which is also an option, however I will have to find a price list.  
Can anyone help me?  It would be driving a high speed modem (most likely a  
V32bis equiped one).

   The Hayes ESP is in the same category, in terms of both performance and 
price, as the larger intelligent multiport cards.  That is to say, it's going 
to be far more effective than a 16550 alone, but it's probably going to cost 
at least $200 Canadian, two to four times what I'd expect to pay for a 
two-port serial card with 16550s.

   The ESP's price is easily explained by the fact that it is an I/O subsystem 
to itself, powered by a CPU and equipped with its own 16550s. You must decide 
if you need the ESP's performance and if it fits your budget.
