Message-ID: <1993Mar10.223556.9363@data-io.com> Sender: bachesta@pugsley (Jim Bachesta) Organization: Data I/O Corporation Date: Wed, 10 Mar 1993 22:35:56 GMT Lines: 19 I'm having a problem with connecting serial devices to com1 and com2 on my 386bsd machine. I have the newest com.c installed (3 patches installed) which I got from ref.tfs.com. The devices are both set at 9600 baud. When my serial device sends relatively large amounts of information (i.e. a hex dump) I lose data. It acts like the flow control is disabled. The serial devices use xon and xoff correctly. I have verifed the ports are set with ixoff enabled. Toggling the ixoff switch make no difference. Is there a problem with the com.c or am I doing something wrong. I would appreciate it if someone could shed some light on this problem. By the way I am using a serial cable with pins 1 2 3 4 5 and 7 connected. I have also done experiments with hardware flow control and I can't get that to work either. Thanks in advance. Jim Bachesta Data I/O Corporation bachesta@data-io.com 206-867-6274
