Exessive interupt over-heads will be apparrent by screen output being noticably slowed down whilst data is comming in at high-speed and sudden emptying of the ISR ring-buffer and fast printing when the other end stops sending after a screen full.

Interupts during a PUSH HL... style CLS routine don't corrupt the screen as on an interupt the PC and whatever reg's get pushed onto the stack which does cause momentry blobs BUT they're popped back off afterwards and the next CLS's PUSH HL's erase the blobs.... The only thing to watchout for is IF an interupt occours just after the final PUSH HL at the top of the screen (as viewed on-screen) then we'd have to make sure we don't have any important data there.. > Ahhhhh.... understood... actually I've planned for this with a script > command called ECHO -- it can be ON or OFF.

The mailer frontend that I'm using on this PeeCee has an earlier versions C source available and may have the Fax receive functions in it as it can receive raw Fax T.4 files itself! I'll get hold off the source tomorrow and have a look see:-) Regards Johnathan ... while(!asleep()) sheep++; -- |Fidonet: Johnathan Taylor 2:2501/307.9 |Internet: [EMAIL PROTECTED] | | Standard disclaimer: The views of this user are strictly his own.
