Thanks for the reply! Your comments got me thinking a little more. As you mentioned the scanner simulates a keyboard to enter the card number. Since reading your post I investigated altering the scanner programming to include a user defined suffix along with each scan. This is possible, unfortunately it appears that I'm only permitted to include a 10 character suffix which is not enough to locate, buy-in and seat the player. Of course.... I need 11!
I can transmit the following suffix along with the scan code - TAB, Enter, TAB, TAB, TAB, TAB, TAB, SPACE - this will successfully locate the player and click on the player check box. However I cannot simulate a tab press enough times to actuate the okay key to finalize the action. Simulating a shift / tab twice would get the job done, but the shift / tab character seems to crash scanning all together. I'm so close!!
I've worked on this for a while and I"m not sure if I'll make it much further. I'll maybe give it a shot one more time before accepting defeat. If anyone knows of a character that will allow a jump from the "player check box" to the "okay" button without having to hit tab repeatedly, that would be extremely helpful. Thanks again!
