Hi All PICers ! b> I'm using a MAX232CPE with a 82C50 to send/recieve b> serial data, i've got reasons not to be using the PIC for b> this. Sending works fine, but receiving gives me a constant b> stream of characters (usually the same one) that aren't b> being sent from the other side (a PC running Telix). b> b> Has anybody experienced anything like this? I'm b> absolutely sure that the software is right, so i'm assuming b> it's the MAX232 or the cable. Philip, check your cable, and try to use another chip. Many times I use this chip, not MAX232 but ADM232 and ADM202 by Analog Devices - its more cheaper then MAXIM, and I have never seen this chip not working! I often use it not only for TTL<>RS232 convertion, but also for providing bipolar power for OP! Best Wishes, Alex Torres. Kharkov, Ukraine, exUSSR.
