That is, it's sort of a VT52 with only 16 lines by 32 characters. I have a Videotex termcap entry (created when my H19 was dead and all I had was Videotex) if you want it. All in all, I think it's really a crock. The program is VERY limited, especially as regards concurrent connection of a printer--600 baud only, and no automatic XON/XOFF to the host when the printer is busy. Unless you have a fast printer, connecting to the host at 1200 baud with the printer running will lose characters. Nice defaults on power-up, too (HALF-duplex?!?) Would that they had added a second RS232 UART instead of this useless terminal ROM. As far as using this with OS9, well it's not clear how you can do it. The Multi-Pak and cartridge ports only support NMI and CART (FIRQ thru a PIA)--no IRQ. I have received conflicting info about what this Pak uses. I wrote to R/S product support and they said NMI, but a quick disassembly of the Pak indicated that it now uses CART. Problem is that in the Multi-Pak interface, only the "selected slot" passes CART to the CPU. I would be interested to hear what your friend has done. Clock polling is possible, too, but I fear that this would only allow rates up to 600 baud (someone tell me I'm wrong, here, please.) /Steve Dyer decvax!bbncca!sdyer
