[ts-7000] TS-7260 and TS-SER4 serial speed issues

["justin_findlay" <>]

I have a TS-7260 running 

Linux ts7200 2.4.26-ts11 #3 Tue Jun 6 14:13:14 MST 2006 armv4l unknown

and a TS-SER4.  I have configured the four serial ports by installing jumpers 
COM1,IRQ2,IRQ4,2-IRQs.  The ports show up under linux as COM1,COM2,COM3,COM4, 
with addresses and IRQs:

ttyS00 at 0x89c003f8 (irq = 40) is a 16550A
ttyS01 at 0x89c002f8 (irq = 33) is a 16550A
ttyS02 at 0x89c003e8 (irq = 40) is a 16550A
ttyS03 at 0x89c002e8 (irq = 33) is a 16550A

This seems interesting to me because the corresponding /dev/ entries seem to be 
/dev/tts/[0-3].  I've set them up with setserial like this:

setserial -v /dev/tts/0 port 0x89c003f8 irq 40 uart 16550A
setserial -v /dev/tts/1 port 0x89c002f8 irq 33 uart 16550A
setserial -v /dev/tts/2 port 0x89c003e8 irq 40 uart 16550A
setserial -v /dev/tts/3 port 0x89c002e8 irq 33 uart 16550A

The problem is that when I connect a serial device to one of these serial ports 
(/dev/tts/[0-3]) the connection is very slow and lossy.  An average response 
time is about 20 s, and I don't get more than about 16 characters back at a 
time.

If I connect the same device to one of the serial ports on the TS-7260, it 
works like normal.  Have I configured the TS-SER4 ports incorrectly?  What can 
I do to fix this connection issue?
