Can it do dial-up to an isp ? Can Native Oberon read A2 files - by mounting the A2 partition ? Thanks, == Chris Glur.

Re. Transfering A2 from one PC's IDE to another ?

Shoot ! My previous post came out mangled via ETH-echo, and my gmail-self-post-confirm. But my N-O self-post-confirm was OK. I'm guessing it's to do with the Oberon. Linux, DOS line-terminators, which arise when using Linux-ETHoberon and V4 together. Many text viewers show DOS & linux line terminators as equivalent, but later processes treat them differently. One of the worst problems I've met is a text editor which, not uncommonly, converts <tab> to <Nspaces>. So that files which need a tab as part of their syntax [like makefiles] fail, strangely !! ========= Previous query:-- Finally the A2 CD boots perfectly on my friends newer PC, where I installed it but could not run it from the IDE, because, in the short time I couldn't see how to make a booter. I've always used a fd0 booter for N-O. And I noticed that A2's Oberon.Text has no dial-up section and no relevant *ial* files. I wanted to test a dialup modem. Does A2 have dialup facilities ? Perhaps because the CDreader which I [seldom] use is marginal with my A2-CD, when I revisit my friend's good PC, I want to: 1. set up his booter for A2, 2. copy his A2 installation onto an IDE [partition] of mine, to hopefully run on my PC. Is this viable ? == Chris Glur. PS. The running A2 may use drivers which don't work when the 'partition' is copied to a different box. I've always been able to copy S3, N-O & DOSbased between boxes. Can my N-O/LinuxETHoberon at least read the A2 files ?

Transfering A2 from one PC's IDE to another ? Finally the A2 CD boots perfectly on my friends newer PC., where I installed it but could not run it from the IDE, because, in the short time I couldn't see how to make a booter. I've always used a fd0 booter for N-O. And I noticed that A2's Oberon.Text has no dial-up section and no relevant *ial* files. I wanted to test a dialup modem. Does A2 have dialup facilities ?

MTU and Ethernet NIC drivers.
by PETER EASTHOPE 07 May '09

07 May '09

Folk, Whereas two NO systems connected to the Internet via Debian Linux receive files by FTP and receive messages by POP3, a sizeable file or message can not be sent. I am considering whether this can be solved by reducing the MTU in NO. Net3Com509.Mod has MaxPkt = 1514. Net3Com90x.Mod has EthernetFrameSize = 1514. NetNe2000.Mod has MaxPacketSize = 1516; (* 1514 + 2 byte padding to 32 bit boundary *). NetBase.Mod has MaxDataLen* = 1514. (1) Are these four constants synonyms? Presumeably they include the MAC header and the CRC checksum. Ref. "http://en.wikipedia.org/wiki/Ethernet_II_framing" "http://en.wikipedia.org/wiki/Maximum_transmission_unit" Length of Mac header = 14. Length of checksum = 4. So, length of payload = MTU = 1514 - 14 - 4 = 1496. (2) Assuming the answer to (1) is "yes" and given that RFC 1191 specifies MTU = 1500 for Ethernet, why was the value of 1514 rather than 1518 used in two drivers? (3) Is NetBase.MaxDataLen = Net3Com509.MaxPkt imperative? If so, definition of MaxPkt rather than use of NetBase.MaxDataLen is bad practice. Correct? (4) Any thoughts on the observed problem in sending non-trivial messages and files? Thanks for any response, ...
