[ltp] IBM 600E, RH9, minicom problem

[Bill Voight]

Sports fans,

IBM 600E, RH9, minicom serial port  Setup- /dev/ttyS0 9600 8N1, Hardware 
flow control, no Software Flow Control

I'm using settings identical to those I've been using on several other 
RH boxes to connect to the A serial port of some U2's.  I am using a 
known good null modem cable and gender bender to connect.  Works fine on 
the desktops, no dice on the IBM 600e.  I've run the diags from the 
600E's bios- they show everything's OK.  Have had no luck with docs- I 
haven't found anything indicating there's anything different about the 
serial port on a 600E.  Setserial output from both is listed below- it's 
identical.  Anybody got any ideas?

Here's setserial output from the desktop:

/root >  setserial -av /dev/ttyS0
/dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4
       Baud_base: 115200, close_delay: 50, divisor: 0
       closing_wait: 3000
       Flags: spd_normal skip_test

Here's setserial output from the laptop:

[root@ibmgeek root]# setserial -av /dev/ttyS0
/dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4
       Baud_base: 115200, close_delay: 50, divisor: 0
       closing_wait: 3000
