I am testing the hub4com software by doing the following:
hub4com on the server with a Conexant D850 56K V.9x DFVc modem
I created a text file for hub4com using com2tcp-rfc2217.bat
I start hub4com --load=my.txt,_BEGIN_,_END_ on the server
On the client, I have:
installed com0com (unchecking the creation of CNBA0<->CNCB0
ran the setup command prompt and installed COM6:
install 0 PortName=COM6,EmuBR=yes -
then I run (from hub4com package):
com2tcp-rfc2217 \\.\CNCB0 myserver 5555
It spits out some communication messages on the client and server and it appears connected
In order to use Dial Up Networking, it looked like I had to create a modem - so I just added a modem "Standard 56k Modem", and then it shows up in the Dial up networking wizard. (am I doing this step wrong? Without adding a modem to that COM port, it doesn't show up in DUN. and if I use Advanced Connection, I see the COM port but I can't enter a number to dial).
So, with the Standard Modem, when I dial out I can see (through our phone system) that the line is connected. DUN then gets to "Verifying username/password" and it times out there (as soon as it gets to that message, I see that the line is dropped in our phone system - so it disconnects right there).
"(loopback)" seems to suggest I'm on the same computer as the modem. But the client (COM6-com0com-CNCB0) is a different physical computer than the server.
Let me know if/where I'm misunderstanding.
Thanks for your help!

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Is using a "Standard 56k Modem" driver on the client "normal"? Or is it recommended to use the actual driver on the client? I tested with the actual driver and it didn't even dial out like it did with the other.
I will run through your recommended tests, thanks.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I ran the test, the "Standard 56k Modem" failed to run on the local box itself, so I stopped there. The Conexant modem was a test before we received our 4-port modem card, so I just stopped testing that modem as soon as our 4-port modem card came in.
The 4-port works great with the com0com/hub4com solution. I ran through the tests locally before trying over the network and everything worked great - including the client/server over LAN.
Thanks for the help.
Jeff
PS - I ended up using the actual modem driver for the 4 port card on the client machine, since it reports the true connection speed whereas the standard always reported a 115.0 kbps speed, and I didn't have any troubles installing the drivers on the client pc with this other modem like I did with the Conexant.

I tried adding "--reconnect=d" in the my.txt file for hub4com on the server, but that made no difference. (I read about that in this post: https://sourceforge.net/forum/message.php?msg_id=3838734\)
What other troubleshooting can I do?
Thanks!

As I understood you trying the folloving:
"Standard 56k Modem" -- COM6-com0com-CNCB0 -- hub4com --(TCP/IP)-- hub4com -- COM1 -- Conexant
and it's not working ("Verifying username/password" times out).
So try the folloving:
"Standard 56k Modem" -- COM1 -- Conexant
"Standard 56k Modem" -- COM6-com0com-CNCB0 -- hub4com --(loopback)-- hub4com -- COM1 -- Conexant
I believe you have my setup correct. I am not following your suggestion however.
> "Standard 56k Modem" -- Com1 -- Conexant
Are you suggesting to add a Standard 56k Modem to the server for the same port as the Conexant?
> "Standard 56k Modem" -- COM6-com0com-CNCB0 -- hub4com --(loopback)-- hub4com -- COM1 -- Conexant
"(loopback)" seems to suggest I'm on the same computer as the modem. But the client (COM6-com0com-CNCB0) is a different physical computer than the server.
Let me know if/where I'm misunderstanding.
Thanks for your help!

I'd like to say that you have multiple points where the bug can be
and it's not a trivial taks to find it.
The first test is for question "Is the driver "Standard 56k Modem" is OK for Conexant?".
The second one is for question "May be w/o network it's OK?".
Both tests should be done with client on the same computer as the modem.
I understand now, thanks!
