There is a commercial version of HX?

Anyway, I have managed to get my COM port working
on Windows 2000 (via Virtualbox). I have a test
program that sends ATZ, waits 5 seconds and then
hopes to see an OK from a modem.

I had Virtualbox com1 enabled, TCP mode, connect
to existing pipe/socket checked, and a path of
news.eternal-september.org:119

Fortunately eternal-september keeps the connection
alive for long enough for Windows 2000 to boot.
I can't really use qemu for Windows 2000 - it seems
that the hard disk drivers are incompatible with what
Virtualbox uses, so I am forced to choose one or
the other. Not sure if there's a way to load Windows
2000 drivers while Virtualbox is being used so that
I can later switch to qemu.

Anyway, the result looks like this:

D:\>comtestw COM1
opening port
sending string
waiting 5 seconds
finished waiting
received 11 characters
received text is:
500 What?


D:\>



ie "500 What?" instead of "OK", because the NNTP
server doesn't know what I'm talking about - which
is fine.


And as noted, under HX, I instead get a return
code of 183 from BuildCommDCB.

But I am impressed that the functions exist at all
and the program loaded.

I guess I need to either make an enhancement request
for the non-commercial version of HX, or add it
myself. Any advice?

Note that the mainframe trying to make contact with
the outside world is like SETI trying to make contact
with Andromeda.
