Well I would imagine that Linux uses /dev/ttyS0 - ttyS3 for serial ports. What does 'dmesg |grep tty' show you?

bingo: tty00 at somehex1 (irq = 15) is a Z8530 ESCC; port = modem tty01 at somehex2 (irq = 16) is a Z8530 ESCC; port = printer

the modem is on. the modem is plugged in to the line. the modem works well in macos.

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. -- The Toronto Linux Users Group.
