>Number: 2405 >Category: kern >Synopsis: PCMCIA support hangs input on non-PCMCIA serial ports >Confidential: no >Severity: serious >Priority: medium >Responsible: freebsd-bugs >State: open >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Tue Jan 7 13:20:00 PST 1997 >Last-Modified: >Originator: Tom Pusateri >Organization: Juniper Networks >Release: 2.2-961014-SNAP >Environment: >Description: When I add the following lines to the kernel config file, the PCMCIA serial port works (sio2) but the onboard serial port (sio1) no longer works. > controller crd0 > controller pcic0 at crd? > controller pcic1 at crd? 82a83 > device sio2 at isa? port "IO_COM3" tty irq 11 vector siointr The output to the onboard serial port works but input doesn't appear to be accepted. It does appear to be transmitted correctly into the serial port but remains buffered in the kernel. If two machines are connected to each other using kermit, and a backslash is typed on the machine with the broken kernel after it has received data, the data is released from the buffer and displayed. If I recompile /sys/i386/isa/sio.c without PCMCIA support, the onboard serial port works fine. >How-To-Repeat: >Fix: >Audit-Trail: >Unformatted:
