Hello fellows. My latest problem relates to one of my TNC based ports. The TNC is a TNC220 in KISS mode, though I am sure that has absolutely nothing to do with the problem, but I'm sure that someone will want that info. The problem is thus: it transmits the same frame, probably 8-10 times, in one big transmission, and because maxframe for that port is set at 3, I quite often see 24-30 frames of 250bytes in length being sent each time the wireless transmits. And at 1200bd, that's taking a lot of time on a shared channel. What could be causing it? The TNC is hooked up to /dev/ttyS1, and I don't have anything else on that irq (3). The TNC is connected to the port via a fully connected RS232 lead - ie: a 25 core shielded cable with D-25's on both ends, passing full continuity checks, no shorts, etc... The other TNC based port on /dev/ttyS2 is working fine. The system is thus: Cyrix MX II PR233, 32Mb RAM. 64Mb swap memory, 4 serial ports (ttyS0-3) using irq's 4,3,10 & 12. USCC at 300h, PC100 at 280h, distro is Definite Linux v7 (a British distro based around RH6.1) with Kernel 2.2.13. ax25-tools-0.0.5, ax24-utils-0.0.4, libax25-0.0.7, node-0.3.0, xfbbd, jnos(g0mhd) 1.11d, clx501, KDE. Installed on 2 x HDD's, 1 x 520Mb, 1 x 1Gb, plus occaisional incursions from a 100Mb Zip disk. Any ideas anyone?
