It is the only one---I've disabled COM2 in BIOS, and according to the manual the external connector is COM1 (mobo is JNF99FL-525). Just tried re-enabling COM2 in BIOS, but that made no difference---both cuau0 and cuau1 remain silent... I'm beginning to think that it might be an `unintended feature' that crept into the UART code... Cheers, -- Igor M.
