File Transfer by modem....

Hi…

I have a modem conection between a Windows machine in one side with a QNX
4.25E machine in the other side. The conection was done with a client telnet
program (netterm) in the windows side and the modem command in the qnx side.

It works fine, but I need to transfer files from the QNX machine to the
Windows machine, and I can´t do that.

With 2 qnx machines I can transfer files using qtalk command. In a tcpip
network I can transfer files using ftp. But what can I do to transfer files
in this kind of conection (serial by modem) ?

I think that a posible solution is using a zmodem command, but how can I
tell QNX that the protocol that must use to file transfer is zmodem instead
of qcp ?

I really appreciatte any suggestions.

Thanks for your help.

There is zmodem on the QNX free software site somewhere. I have also used
Kermit successfully for this. The terminal program that comes with Windows
supports the Kermit protocol, and there is an up-to-date Kermit available
for QNX 4.25 at the Kermit website. It is not freeware, however; I think it
is about $60.

After doing qtalk to the serial port:
ctrl-A
will bring up a menu.
Select ‘t’ for “t)ransfer protocol”.
In there, you can choose qcp/zmodem/other.

Thanks for your help…

I know that I can change the transfer protocol from qtalk, but I can´t load
qtalk. I get the message: serial port in use.
I believe that is because the “modem” command is using the serial port.
Remember that in the QNX side I use the “modem” command to make the
conection.

Any other idea ?

I thanks again for your help.

modem should not hold the device open.

try “stty -a < /dev/ser1” to check the opens.
try “sin fd” to see what processes have fds to the device.

Which way are you connecting/dialing?

G-Kermit is a free, open source version of Kermit. It doesn’t have all
the bells & whistles of C-Kermit, but it is small and very reliable. I’ve been
using it for some time. Both G-Kermit and C-Kermit are available at:

http://www.columbia.edu/kermit

If you would prefer to use C-Kermit, you can pay for a license by buying a
copy of the book “Using C-Kermit” by da Cruz and Gianone.
