I'm using a 16 port BOCA multiport serial board on my FreeBSD (950726) machine. There seems to be a bad flow control problem (drops about 50% of the characters) with any modem I put on the BOCA board. I put the modem on com port 1, and it worked fine. I've played with stty and it didn't seem to help at all. The boca board is on irq 10 and starts at port 0x100. This is what I have in my kernel config file: options COM_MULTIPORT device sio0 at isa? port "IO_COM1" tty irq 4 vector siointr device sio1 at isa? port "IO_COM2" tty irq 3 vector siointr # 16 port BOCA board device sio2 at isa? port 0x100 tty flags 0x1001 vector siointr device sio3 at isa? port 0x108 tty flags 0x1001 vector siointr ... device sio15 at isa? port 0x168 tty flags 0x1001 vector siointr device sio16 at isa? port 0x170 tty flags 0x1001 vector siointr device sio17 at isa? port 0x178 tty flags 0x1001 irq 10 vector siointr Any suggestions? -- Brian Koehmstedt bpk@kern.com
