[RTTY] USB to Serial Convertors

[Andrei Stchislenok]

Rich and all:

I purchased this dual port converter and another one (dont remember the
brand) just accidentally.
"Another one" did not work, but this Dual port converter worked as soon as I
installed its drivers. I have been using this converter since then. I am
using Writelg and MMTTY, good combination for me.

Tried different programs, they work too...

The reason why I bought it, was that I have laptop with one Serial port, so
I needed another comm port.

It works for me. I used it from home, YN2S location twice, from HQ4R and
others, so far so good...

Belkin is OK too, but too big, (hi) and have just one comm port...
