Title: IBM M122, and its rollover capability
Post by: Goffredo on Tue, 12 February 2019, 15:41:52
Hi all,

I am using a IBM M122 keyboard with the Soarer's converter. It works quite well. However I was disappoint when I discovered that some "basic" key combination didn't work: eg (left) CTRL-S and (right) SHIFT+LEFT. If I look to the debug information of the converter I see:
LCTRL-S:
r11 +E0 (LCTRL) dE0 (LCTRL)
rF0 r11 -E0 (LCTRL) uE0 (LCTRL)
( I don't see the 'S' make/break code)

RSHIFT-LEFT:
r59 +E5 (RSHIFT) dE5 (RSHIFT)
rF0 r59 -E5 (RSHIFT) uE5 (RSHIFT)
Same as above: the LEFT (arrow) key is not send.

My question is: it is normal? CTRL-S and SHIFT-LEFT are quite useful keys combination. It is possible that these are not working ?
