This gets you two hardware serial ports and, even though the 8530 is a real bitch to program, it's lots better than the software UART. Don't know about QTERM, but there's a ZMP overlay for this configuration. .....Ron -- =============================================================================== Internet: Murray_RJ@cc.curtin.edu.au | "The Universe is so Bitnet: Murray_RJ%cc.curtin.edu.au@cunyvm.bitnet | utterly disorganised UUCP : uunet!munnari.oz!cc.curtin.edu.au!Murray_RJ | that it can only have Amateur Packet Radio: VK6ZJM@VK6BBS.#WA.AUS.OC | been written in Pascal" TCP/IP: 44.136.204.14, 44.136.204.19 | -- The Phantom Waffler ===============================================================================
