- 88-MODEM OPERATING INSTRUCTIONS:
-
- Detailed operating instructions for this program are contained
- at the beginning of the source listing (88-MODEM.ASM). Additional
- instructions are contained in the publication "DR. DOBBS JOURNAL OF
- COMPUTER CALISTHENICS & ORTHODONTIA" VOLUME 3, ISSUE 6 (June/July issue).
- The program has been updated since its publication in
- DR. DOBBS. as follows:
-
- 1. The "handshake" character has been changed from
- "ETX" to "LF". This should make it almost univer-
- sally applicable.
-
- 2. The DELAY routine has been changed to make it hardware
- independant.
-
- The only remaining hardware dependant feature of the program is the
- "ASSIGN CONSOLE DEVICE" (^A) which provides for reassigning the console
- device. This function assumes a TDL ZAPPLE MONITOR.
-
- As mentioned in the DDJ article: If a printing terminal is
- used as the console device, it must be capable of operating at twice
- the selected communicationa baud rate when disk transfers are per-
- formed. Additionally, data loss may be encountered - even at a low
- baud rate - in RX FILE mode if the disk controller does not provide
- for DMA.
