Hi,
in addition to my last post i tried to debug this problem, but my Knowledge
about C is too poor.
Anyway i added a debug-line in File session.cc as follows :
....
int LATSession::read_pty()
...
msglen = read(master_fd, buf, max_read_size);
// ------- for testing
debuglog(("**** Session : %d From PTY(%d): '%s%s'\n", local_session,
msglen,
buf, (msglen>10)?"...":""));
...
and got the following debug-logs
Debug-log of the working - connection (Command : "dir g* >/dev/lat/TS703")
32: LocalPort::do_read(), connected: 0

The first example prints on the port as it should, the second produces no
output.
I stuck here - hope anyone can help.
