You hijacked a serial port? What's it being used for otherwise? Ever think of adding another serial port? Having had modems since 1200 baud full duplex was exotic the most important thing I've learned is that a modem is a throw-away disposable sacrificial component. It has no business inside the computer where it can do damage to other components when (not if, but when) it blows up. If your serial ports are being used and you have a slot, then add more serial ports: sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0 sio0: type 16550A sio1 at port 0x2f8-0x2ff irq 3 on isa0 sio1: type 16550A sio2 at port 0x1a8-0x1af irq 10 flags 0x205 on isa0 sio2: type 16550A (multiport master) sio3 at port 0x1e8-0x1ef flags 0x205 on isa0 sio3: type 16550A (multiport) sio4 at port 0x2a8-0x2af flags 0x205 on isa0 sio4: type 16550A (multiport) sio5 at port 0x3e8-0x3ef flags 0x205 on isa0 sio5: type 16550A (multiport) Notice the last 4 are on a card which is capable of correctly sharing one IRQ for all of its ports. The card is a long discontinued STB 4-Com. Nothing fancy about it, contains one Startech ST16C554CJ which I've seen on a number of serial cards including some cheapies from Jameco. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
