Problem with MUX card.
When this hardware was used on HP-UX 10.20 everything was Ok, but afer migration to another box with HP-UX 11.11 approximately 1 of 25 answers from serial device is lost.
BTW, there are two type of messages software process can send to the serial device. Messages of one type are successful 100%, problem is with second type messages only :(
I checked line between serial device and MUX and I saw that there is answer going from serial device, but software process doesn't know about it.
I suppose there is something wrong with MUX configuration. Can anybody give me an advice?
Thanks in advance
Best Regards

Re: Problem with MUX card.
1. 19 bytes request to serial device;
2. 7 bytes response from serial device;
Second type of messages is:
1. 42 bytes request;
2. 24 bytes response part 1;
3. 7 bytes response part 2;
I don't receive any response from serial (neither part1 or part2).
I'm not sure if this card is certified with 11.11 but it seems to be.
How can I check buffering settings of the card?
2ravi: Sorry for stupid question - Can you point me which patches are necessary and where can I download them.
Thanks in advance

Look at the major and minor numbers on the tty device to make sure you are talking to it the way you were on the 10.20 box.

Re: Problem with MUX card.
This actually sounds like classic handshaking problems - especially since the smaller 'first' type messages always work but the larger messages sometimes don't.
You need to do a stty -a < /dev/ttyxxx on the port in question and look especially at the ixoff,ixon,ixany settings and if using hardware handshake ctsxon and rtsxoff.
