W8SDZ@Simtel20.ARPA (09/08/84)
From: Keith Petersen <W8SDZ@Simtel20.ARPA> MXO-KP28.ASM is a new MEX Overlay for Kaypro Computers with either internal or external modems. A full-featured SET command processor is implemented to select between modems as well as set specific characteristics of each one. The file is now available from SIMTEL20: Filename Type Bytes CRC MICRO:<CPM.MEX> MXO-KP28.ASM.1 ASCII 37584 D19EH The following table outlines the SET command options: Available for SET Command Internal External INTERNAL YES YES EXTERNAL YES YES DELAY <n> (seconds) YES YES BAUD <rate> NO YES ORIG (originate mode) YES YES ANSWER (mode) YES YES TONE (dialing) YES YES PULSE (dialing) YES YES MONITOR (speaker on) NO YES QUIET (speaker off) NO YES PARITY (Odd, Even, None) NO YES STOPBITS (1, 1.5, 2) NO YES LENGTH (5, 6, 7, or 8) NO YES MANUAL (goes off-hook and YES NO activates modem) Recent revisions: 8/26/84 2.8 Added equate to support Anchor Signalman Mark XII modem. This overlay now supports DSC, dial abort (^C), and accurate SET DELAY processing for Anchor modems. Also incorporated the PARITY, STOPBITS and LENGTH commands from the Norm Saunders overlay (MXO-KP3X) in an attempt to unify the Kaypro MEX overlay identity crisis. The new SET commands are NOT implemented for the 4'84 internal modem. The SET ? command and the SET without arguments correctly distinguishes between the internal and external modem support. Terry Carroll 8/03/84 2.7 Added call to DISCON: (disconnect routine) in the Smartmodem dialing routine at SMDMOFF:. It appeared that when either the delay timer timed out or a CTRL -C abort coincided with a connect, the modem did connect, even though the overlay responded with NO ANSWER. Added these calls to make sure there is no unannounced connect. John C. Smith --Keith
