From: Keith Petersen <W8SDZ@simtel20> The ^P in the terminal mode SHOULD work correctly IF you have LISTSTAT implemented correctly in your CBIOS. This is the new CP/M 2.2 vector in the CBIOS jump table that tests to see if the printer is ready. MDM712 relies on this routine to prevent loss of characters. MDM712 should issue an X-OFF (^S) to the mainframe when the 16k printer buffer is full and then it should gather up to 128 ADDITIONAL characters in an auxilary overflow buffer while waiting for the mainframe to honor the X-OFF request. This feature has been in MDM7xx for a number of versions and there have been no problems reported. Your problem with the terminal mode not allowing use with screen-oriented text editors is caused by an option in the user overlay not being set correctly. The distributed overlays all have a "filter control characters while in terminal mode" option TURNED ON. You must re-assemble your overlay with a NO there instead of a YES. --Keith
