Problems with receiving a file via 'qcp'

While trying to use QNX6 to connect to a QNX4 system via qtalk, for legecy
support issues. I wanted to transfer a file back. When I issued a ‘qcp se’
on the remote system it dropped the line and terminated qtalk. I then tried
the same thing from a QNX 4 system and it worked just fine.

The modem on the local system was on /dev/ser1. I have also tried it with
and without photon running.

Anybody have any ideas?
