Title: FTP copy hangs while running LLI drivers under SCO 5.0. Product: SCO 5.0 Problem: A kernel parameter needs tuning when running LLI drivers under SCO 5.0. Symptom: Attempting to FTP a large file (>4096 bytes) causes the FTP process to hang after transferring 2920 bytes. Solution: Get into the "System Administration" folder under SCO DeskTop and double click on the "Hardware/Kernel Manager" Icon. Select the "Tune Parameters..." button and choose the STREAMS parameters option. Press enter to answer all questions except for the parameter "STRMAXBLK". The default value will probably be set to 524288. Change this to 4096. Relink the kernel and reboot (follow the Hardware/Kernel Manager instructions). Caveat: Unless you have patches to get you to SCO 5.0.0d, some X clients may break with the low STRMAXBLK value.
