I have discovered 'setserial' and z8530-utils.deb...

(kernel seems not to recognize the device tty00 which it listed in dmesg:)
# setserial /dev/tty00
Cannot get serial info: Inappropriate ioctl for device

(/dev/ttyS0 is recognized as the somehex1, irq=15 address:)
# setserial /dev/ttyS0
/dev/ttyS0 somehex1 UART unknown irq=15

I think I am close here.  I connect /dev/modem -> /dev/ttyS0 and try my 
chat file to no avail.  I have no response when I send "ATZ (OK) ATDT 
4165551212".  I should add that the macos has no trouble with ppp dialout.

The setserial (+ manpage) does not recognize "z8530" or "8530" as valid
entries to UART.  I should add that my machine is a powermac
750/267mHz/OldWorld machine if anyone thinks it would be useful 
administrivia.

TIA, 
max.
