Hi, Use the 16C554 Peter Schultz -----Original Message----- From: James & Ili [SMTP:jandi@MPSI.NET] Sent: Thursday, March 26, 1998 6:26 PM To: PICLIST@MITVMA.MIT.EDU Subject: Serially programmable C54 ? Hello, I was wondering what would be a direct replacement for the 16C54 in a serially programmable model ? Would the 16C61 work ? I really don't want to have to modify the code if at all possible. Thanks !! James & Ili Irving, TX. 75038
