Dave, We know that the keyboard driver has to be disabled and know how to disable the driver. Say, soft reset when the cradle is hooked up would be good enough for now. And an appropriate level shifting cable is used to interface our RS-232 device. I need to know for sure if the Visor could sustain 115K communication speed. Is it possible at all?
HermesPalm wrote in another reply: "... they changed the name of the serial library". Could it be that they changed the library itself? Does the Handspring serial library is equivalent to New Serial Library? Does it include SrmSetWakeHandler, SrmReceiveWindowOpen, SrmReceiveWindowClose functions compatible with those in Palm OS New Serial Manager? Thank you guys for the replies in any case. ----- Original Message ----- From: "Dave Lippincott" <[EMAIL PROTECTED]> To: "Palm Developer Forum" <[EMAIL PROTECTED]> Sent: Friday, September 06, 2002 6:15 PM Subject: Re: Handspring Visor and serial driver > Visors have a keyboard driver running.
