- Hi,
- We use tn3270(cutcp) on our old PC-AT to communicate with IBM3090 and SUNs
- on ethernet. It works alright, but every once in a while the PC freezes and
- requires a reboot. It seems that data is coming too fast for the pc to
- handle. I wonder if I can tinker the CONFIG file in some way to make the
- communication more reliable (don't mind the slowdown). Your advice will
- be greatly appreciated. please answer by e-mail, if possible.
- --Sanjay.
