ZBasic Forum

Anyone know how I can buy module(s) rather than spin a PCB, to obtain a ZBasic processor with a serial port supporting, as RS232:

TD, RD
RTS, CTS
DCD, DTR

These are needed by the devices with which I would like to interface.
(and not have the ZX "ATN" line involved at all)

Seems like all products omit DCD/DTR as these are usually modem controls - not so in my application - they're used as screwball signals by the peripheral device (weather stations)

I don't know of anything right off the top of my head. The 1280 development board has a seconds DB9, but the schematic shows just "TX " and "RX" as being connected to the RS232 converter.

a major kludge might be to split the one RS232 cabe into 2 ends on the ZX side to make use of the 2 extra channels..... But I think that still only gets you 4 channels.

You say you do not want to make a hand-made 6 channel rs-232 converter module? Something could be pretty easily done with some strip board, or something similar.


I do not recall any BX-24 development boards which offer full rs-232 support, but maybe one is out there. Some development boards which are compatible with the ZX-24 have a little breadbord area that you could use to assemble the rs-232 interface?
