I just found a Hayes ESP card I bought quite some time ago.  It's a single
port ESP, marked "V2.1".  It has only one jumper, presumably for the ESP
base address, which is set to "soft".  I recall software-configuring the card
to COM3 the last time I played with it.

I threw it in my machine, and it was detected on com2 as a 16550a.  I looked
at com.c a bit, and tried turning on the COM_HAYESP option; still no dice.

What do I need to put in the config file to get this card working with the HW
flow control and larger FIFO?
