Several weeks ago there were some postings about the Maxpeed intelligent serial controller card and bi-directional serial communications. The stated result was that the Maxpeed card would not work properly with ISC 2.02 and modems running bi-directionally on single ports. This is incorrect. As fate would have it, I was in the process of bringing up a Maxpeed card at the same time that the Maxpeed serial bug postings came across the net. I do not remember who made these postings, but thank you very much! The warnings saved me a lot of time. From this end, the card was brought up, setup and verified that it would not work (simply, at least). Technical support at Maxpeed was immediately contacted. Here is what you do to make a Maxpeed card work bi-directionally, which works flawlessly both directions, by the way: [Note: ttyaa & ttyaA are used as examples only.] 1. Go into sysadm, select package management, select uucp and setup ttyaa (Note: ttyaa, NOT ttyaA). When asked to select the kind of communications, select bi-directional. 2. Edit /etc/inittab. All you want to do here is exchange the ttyaa and ttyaA entries so that uugetty is running on ttyaA. 3. If uugetty is running on ttyaa, kill the process and execute an init q to bring up uugetty on ttyaA. 4. Edit /etc/gettydefs and change CS7 to CS8 and remove PARENB on whichever entries are necessary. A sample of an old and new 2400 baud entry is shown below: OLD----- 2400# B2400 OPOST ONLCR TAB3 BRKINT IGNPAR IXON IXANY PARENB ISTRIP ECHO ECHOE ECHOK ICANON ISIG CS7 CREAD # B2400 OPOST ONLCR TAB3 BRKINT IGNPAR IXON IXANY PARENB ISTRIP ECHO ECHOE ECHOK ICANON ISIG CS7 CREAD #login: #2400 NEW----- 2400# B2400 OPOST ONLCR TAB3 BRKINT IGNPAR IXON IXANY ISTRIP ECHO ECHOE ECHOK ICANON ISIG CS8 CREAD HUPCL # B2400 OPOST ONLCR TAB3 BRKINT IGNPAR IXON IXANY ISTRIP ECHO ECHOE ECHOK ICANON ISIG CS8 CREAD HUPCL #login: #2400 5. Edit /usr/lib/uucp/Devices. Change the entry for ttyaa to ttyaA and add an entry showing a direct connection to ttyaa. After all of these changes, everything should work just fine. If there are still problems, then take a look at your modem settings and check cable connections. I have no affiliation with Maxpeed and have provided the above information for the sole purpose of helping a few people keep their sanity :-). Gary Lewin USMAIL: P.O.
