AAArrrrrggggghhhhh! I have an AT&T 6386E/WGS equipt with a IPC-802 multi-port card. I have SVR3.2.1 and the driver version 3.0 for the card. The book for the card says that when you open the ttyhxx device for the port it will do hardware flow control. the ttyhxx device for the same port is for software flow control only. I open the ttyhxx device O_NDELAY and then after dialing the modem I unset CLOCAL so that I amd using the modem hardware lines. This Activates the DCD sensing capibility just fine but inorder to get the RTS/CTS behavior I also then have to set IXON. This too works fine (after a fassion) but this setting not only operates the CTS line, it *SENDS XOFF/XON CHARACTERS* I do not like this. This driver is *broken*!!!! Is there a way I can either 1) get a good driver from somewhare, 2) set the XON/XOFF characters to some ilegal value so that no characters will be generated, or 3) activate the hardware flow control from another angle to prevent the extra and unwanted software signals. (I do know that it is the card driver and not passthrough from the operator terminal or anything....) -- Robert C.

Evil followup of own posting: /dev/ttyhxx is hardware /dev/ttysxx is software /dev/ttyhxx "the presence of the CTS signal enables the IPC-802 transmitter and the presence of the DCD signal enables the the IPC-802 enables the receiver." Translated: If you are sending bulk data out you will be hardware flow controlled correctly, but when receiving the data you will not be (unless you have IXON set) able to flow control. Typos aside, how can I get hardware flow control out of my card without sending the ^S^Q along with the real(tm) hardware flow control? I may be asking for undoccumented features or something, but I need what I need. -- Robert C.
