My kernel and setserial say:

Nov 13 20:54:03 redrose kernel: POSIX conformance testing by UNIFIX
Nov 13 20:54:03 redrose kernel: Serial driver version 4.20 with no
serial option
s enabled
Nov 13 20:54:03 redrose kernel: tty00 at 0x03f8 (irq = 4) is a 16550A
Nov 13 20:54:03 redrose kernel: tty01 at 0x02f8 (irq = 3) is a 16550A

[redrose]/usr/ftp[12]# setserial -V /dev/cua1
setserial version 2.10
[redrose]/usr/ftp[13]# setserial /dev/cua1
/dev/cua1, UART: 16550A, Port: 0x02f8, IRQ: 3

Output of setserial looks different...

I honestly can't find any occurrences of rc.*serial, base RH 3.0.3.

Never had any PPP problem. I tried setting it to spd_vhi, it keeps
working. modem is a noname-28800 (PowerCom), when ISP is fine it gets
to 3.1K/s.
