Ahah - it looks like you are experiencing Jochen's problems.
The best way of testing is to connect ser1 to ser2, and ser3 to ser4
with pin to pin leads. Then the following will test
(this is QDOS - so will have to be translated to SMSQ)
10 test$="The quick brown fox sat on the lazy dog"
20 OPEN #1,ser1:OPEN#2,ser2
30 FOR j = 75,150,300,600,1200,2400,4800, .... and all valid values.
40 BAUD j
50 PRINT j;' - '
60 PRINT #1,test$:PRINT#2:test$
70 INPUT#1,a$:IF a$<>test$:PRINT 'SER1 error':STOP
80 INPUT#2,a$:IF a$<>test$:PRINT 'SER2 error':STOP
90 PRINT 'OK'
100 END FOR j
and repeat for ser3/4
This is pretty well what Thorn-EMI did when they were testing the serial
ports in production.
