My environment: I'm running a 25 Mhz 386 with a Seagate ST277R-1 65MB 28ms RLL drive. I'm using a WA6-VR 1:1 controller with disk cacheing. My modem is a USR Courier HST dual standard. My problem: When transferring files at high rates (9600, 14400), I encounter frequent errors (like every other block) using ymodem or xmodem. A friend told me that the disk cacheing is to blame because interrupts are disabled while the cacheing is being executed and at high bit rates I'm probably missing characters. Can anyone confirm that this is true? If it is true, is there any way to temporarily disable the disk cacheing short of wiring an external switch to the jumper on the controller board?
