Это поможет решить описанную мной проблему с вставанием модемов в
ракообразную позу?

Даю дополнительную информацию. В startup-config у меня 

line 161 190
 session-timeout 10
 access-class 2 in
 flush-at-activation
 modem InOut
 modem autoconfigure type mica-vas
 transport input telnet
 autoselect during-login
 autoselect ppp
 stopbits 1
line aux 0

А в running-config откуда-то появились непрошеные строчки:

line 161 190
 access-class 2 in
 exec-timeout 0 0
 timeout login response 0
 flush-at-activation
 modem InOut
 modem autoconfigure type mica-vas
 data-character-bits 8
 exec-character-bits 8
 special-character-bits 8
 length 0
 width 0
 no history
 no editing
 transport preferred none
 transport input telnet
 escape-character soft 0
 escape-character 0
 no ip tcp input-coalesce-threshold
 autoselect during-login
 autoselect ppp
 hold-character 0
 lat out-group all disabled

А вот что говорит "sh line" на линии с ракообразно стоящим модемом.
Что там такое странное в районе  special Chars ?
