- QCOM is a small library of RS232 communications routines supplied as a
- TP version 5.5 TPU. As of this date, version 5.5 of the compiler is
- definitely required in order to use this material. The supplied software
- is copyrighted by Alpac Systems and Finn J. Nielsen, 1741 W. Orchid Lane,
- Phoenix, AZ 85021. The software may be freely distributed as the complete
- archive uploaded on this and other bulletin boards. Use in commercial
- products is not permitted without the express permission from Alpac
- Systems.
-
- QCOM is an entirely interrupt driven package. Both input and output
- communications take place through interrupt driven queues. Baud rates up
- to 38.4K bits are supported, although rates over 9600 baud may be
- unreliable on certain PC's (such as 8088 based or slower 80286 based
- machines).
-
- COMBAR is a small test program (source supplied), which exercises QCOM
- in a turnaround test. In order to use this program, a PC with at least
- two asynchronous ports is required. The two ports are connected together
- with a standard "null modem" cable. The program dynamically displays
- the flow of data through the two ports in a couple of bargraphs. Line
- speeds up to 38.4K bits are tested.
