AST RESEARCH, INC., TECHNICAL BULLETIN #TB-0380 02-17-88 AST-3780 AND AUTO-DIAL MODEMS A customer has a requirement for un-attended operation of the AST-3780 product. The need is to send a string of characters to the modem via the AST-3780 software to dial a phone number to start the RJE session. The problem is that the AST-3780 software pads any blocks that are shorter than 80 characters with extra characters. The modem does not know how to handle these characters and does not function correctly. The AST-3780 product does not have the capability to perform this function.
