errno = 16 using DIGI TS 8/16 modem switch

[Bob Barram_1]

I saw the thread on this error and recreated the device and got the same error. I switched modems thinking it might be hardware but still got the same error. I checked the digi switch and saw no errors reporting. Any other ideas?
This is the reporting line:
root@rachp1:/dev# call2 /dev/ttya03 r02004

Yes, I saw that and tried the solutions but still had the problem. I ended up switching to an unused port on the Digi and it worked. Seems there is a problem with that one port on my Digi.
