Hardware Flow Control on AIX 5.3

Serial Servers & Infrastructure Mangement Portserver TS
1

I have configured a port on my Portserver TS8 using realport for AIX 5.3. Yet my software program, Esker’s vsi-fax throws the following error (see below), when trying to set hardware flow control.

lkwdev1:/# vfxadmin device -u -Q hard fax01
vfxadmin: Hardware flow-control mode not supported on this platform,
software flow control will be used
Device fax01 updated

I don’t expect debug of Esker’s problems, but I wanted to post my port config below and see if there is something incorrect with my settings. This port is being used for outbound faxing only w/ vsi-fax 6.0 using a MT5634ZBA series modem. Please let me know if you see a glaring error. Thanks!

The settings look perfect.

The error is clearly related to the Esker software.

The configuration can be tested fairly easily by using something outside of VSI-Fax:

  1. Turn the modem on.

  2. Access a root prompt on the AIX system. Add an entry for the device in the file /usr/lib/uucp/Devices. The following example allows a connection of 19200 baud to the device:

Direct tty5 - 19200 direct

Use the following command to connect to the modem:

cu -ml tty5

Use ATDT(phone_number) to call another modem that will allow you to login to a host (perhaps a modem on the same AIX host?). You can then send or get files using the ~%get or ~%put commands.
