I'm having a problem with the AT&T PC 6300 and 6300 Plus. If anyone can help me, I'd be most appreciative! I can't seem to get the "underscore" character mode to acutally use underscores. On an ordinary dumb terminal (vt100 compatible), I can send an escape sequence to turn on underscore mode. When I send this sequence on the pc's (using CrossTalk and vt100 emulation), the characters simply appear in a different color; there are no underscores. I'd like to believe that the monitors are capable of displaying a character with an underscore. I just can't figure out how to do it. The only manual I have available is the User's Guide and it's not very helpful. Thanks in advance for any help. Scott D.

Olivetti "corretly" emulated the yucky attributes of the IBM CGA card on their P6 and P8 indigenous video controller boards on the 6300 and 6300+. The olivetti faithfullness of emulation includes the lack of true underlining whilst in RGB output mode. The blue gun bit is customarily used to indicate underlining. If you have an AT&T monochrome monitor and turn the blue gun on, voila, you'll get underlining; on an RGB monitor, you'll get blue letters. There isn't an easy way I know of (but it would be quite easy for me to be wrong) of faking out the video controller and convincing the controller to do underlining on and RGB display, thought the controller is perfectly capable of doing so, without actually plugging in the correct type of display. The video mode is controlled by a sense lead on the 25 pin plug that to the best of my knowledge is not software addressable. I suppose one could concoct a gender bender that woudl lie to the controller about the type of monitor installed. I beleive the mono and RGB tubes are both 25 KHz * 60 Hz noninterlaced so it should work.
