[Trlog] Multiple serieal ports for a laptop

[Mark Bailey]

Hi Bob:

Can you use a desktop?  Byterunner, for instance,
makes some very nice PCI dual serial cards which
have very nice DOS drivers.  (I have never
tried their quad serial card, but it probably
works too).  I use these dual cards with TR-Log.
Heck, when I got VY2TT, I take a couple of these
cards and plug them into his computers!  :-)
(www.byterunner.com, PCI-200L dual serial card).

Laptop PCMCIA serial cards are problematic under
DOS, quite susceptible to RF interference, and very
difficult to find with any SUPPORTED DOS drivers.
I am unaware of ANY USB to SERIAL converter with
DOS support, though there may be one.

73,

Mark, KD4D
